  1. hey guys I have a 2003 hummer h2, I want to get new shocks as I haven't changed mine at all. I am looking for the smoothest ride possible. I do not off road or tow. just normal city and highway driving. I'm kinda on a budget so don't wanna get Bilsteins or rancho. I'm looking at these: Gabriel Ultra (heard there stiff) Monroe Reflex Kyb Gas a Just KYB Monomax (heard there stiff) so I believe it's between the Monroe reflex and the kyb gas a just or anything else in similar price range. what do you recommend for the smoothest ride? thx
  2. hey guys, my 6.2l v8 with 340,000 km has a misfire only at idle on 8th cylinder (p0308), it doesnt start right away but if im stopped for around 15-20 seconds it will start. i know for sure when i manually raise the idle by foot it doesnt misfire. the truck never misfires at speed or on highway, drives smooth as butter. i swapped coils with working coils, put in new plugs, and swapped wires. had a indie look at it and he said leakdown and compression was good, so he thought had to do with intake gasket but wasnt the case. i took it to gm, and they disgnosed and they believe its a mecahnical problem, something with the camshaft or something, ill get the full diag in a couple days. so i wont be repairing the engine or replacing it unless it was gonna be a cheap repair, im just gonna drive till it dies and then get something new. so i was thinking of using my tuner and raising the idle rpm to idk maybe 700-750 and hope it hides the misfire? if not raise to like 800-900 until it stops misifirng. is this a fine idea? or am i doing more damage then not? i am certain it will stop the misfire for idk how long because when i do that manually with my foot it doesnt misfire or will stop the misfire. i was also reading and someone said it has to do with oil passages getting clogged and the play with the camshaft increases which makes vvt wonky and causes the misfire? sounds kinda like what gm said since they said its an internal engine issue. thx!
  3. hey thanks a ton for your reply, yeah sorry i meant 6% leak down aha. perfect ill take a look for injector pulse and also the vacuum leaks !
  4. I’ll try a live scan tool, never used one before so I’ll see what’s up! Thanks! never swapped injectors before, is it relatively easy and do I need some more tools? and yeah I fill 91 to 94 octane lately hoping to stop the misfire but nothing
  5. also mechanic said he did a compression test too and was getting 200+ each cylinder, he doesnt remember off the top of his head but he doesnt think compression is a problem
  6. hey guys, got a 07 escalade with the 6.2l v8. its got 335,000km on it and has been running great, never had any engine issues other then the piston slap and noisy lifters so the thing is whenever i come to a stoplight and stay stopped for like 15-20 seconds, ill get the message that says " stabilitrak off service traction control" and then the tone of the engine will change and i guess it will sound rougher with a shake, but right when i start driving agian it goes back to normal and then message clears. if i go on the highway, it drives perfect, smooth, good power good revs and never triggers a messsage or anything, but when i come a stop light or any stop, if i wait long enough it will do its thing again.. rough idle, stabilitrak message, and also if i wait like a minute or 2, then the check engine light starts flashing as well, i believe this is because the truck thinks its misfiring or is misfiring and thats why the check engine light flashes. so im not a mechanic on my own but i swapped coils and tried to see if the misfire stops and it doesnt. i also swapped the plugs around and still has the same problem. the plugs and wires are relatively new only 50,000 km on them. i used my code reader and traced it as a p0308 so i swapped a brand new spark plug into that cylinder and still has the same problem. but have showed it to a local indie mechanic and he did a leakdown test got 94% so he said the engine is still strong, he changed the gasket on the intake manifold i believe but hes stumped otherwise anyone have any luck? i was reading more and someone said when the engines get gunked up and old, the vvt goes wonky and ends up causing this? but not sure if thats the truth thx!!
  7. my mechanic did a leakdown test and said he got 94 something and said it was good, he also did compression test and got good compression, he said he cant remember numbers but it was above 200 each cylinder. he replaced the intake manifold gasket and that fixed the problem temporarily but it seems to have came back. anything else we should try?
  8. hey guys in my 2007 escalade, the wiring harness that runs near the transfer case got caught up around the driveshaft and it ripped the wires apart. now i have troubles starting somedays, no fuel level and who knows what other problems. the truck seems to run fine tho. my mechanic said he can splice the wires but he said that the connector is broken and we need that to get it working. he went to gm but they were no help. anyone have anything that can help us? maybe even the whole part number for the harness or something, or schematics for which connector that is
  9. Thanks for the reply. I got the metal bracket off and out of the way, it moved downwards so I now I can make direct contact. I tried to grab with needle nose pliers but it loses grip, I even tried with vice grips. Those hold on good but it doesn't move. It seems like I can get best access from the top of the engine, there's a lot of space there. The vice grips make great contact but I guess I have to pivot Is it ok to try from the top? Or have to be from bottom thanks
  10. 2007 escalade 6.2L, i got the 3 bolts on holding the camshaft position sensor bracket, and then i applied some penetrating oil to get the CPS to start wiggling side to side, but I cant seem to get it out, ive tried pulling it out with vice grips and pliers but it doesnt seem to want to come out. i guess the rubber o ring keeps it in there good.any tips
  11. thanks for the reply, i only had 5 mins today with the truck and i cleared the code and it starts for 1 second, but then it shuts right off. it still has the p0461 code, i will check the other wiring tomorrow unless it starting and shutting off means something else
  12. yes it guranteed has gas, i just filled up 60l two days ago, so your guessing it must be a different sensor? The manifold absolute pressure (MAP) sensor The air conditioning (A/C) refrigerant pressure sensor The accelerator pedal position (APP) sensor 2 The engine oil pressure (EOP) sensor The camshaft position (CMP) sensor
  13. 2007 ESCALADE ext, in midst of fixing my misfire issue. and lately the truck has also been getting the reduce power message with the engine not starting. it happened last month for the first time, i was on the highway after driving about 100km, the reduce engine power came up and i pulled over. i didnt have a code reader or any tools, but after shutting off it wouldnt start anymore, and then i finally got it started with the reduce engine power message and drove it 500km home, it let me drive in manual, and when i went to fill up gas, the message went away and i was able to drive home normally.however my fuel tank still showed empty, and it kept saying fuel low. the truck wouldnt start the next day, and i was away for a month but when i came back to it a couple days ago, it started up just fine. well today i was at the grocery store but it wouldn't start backup. i plugged in my code reader and it came up with p0641 something about 5v and also p0463 which is fuel level sensor circuit high. so im guessing the connection between the 5v and the fuel level sensor is cut or broken? is there any way i can bring the truck home tomorrow without having to tow it? im gonna try starting it up tomorrow morning from the grocery store hoping it can limp home. thanks
  14. could this be regarding to the evap codes ive had for a while? maybe the leak got worse? P0036 HEATER CONTROL CIRCUIT BANK 1 SENSOR 2P0056 HEATER CONTROL CIRCUIT BANK 2 SENSOR 2P0449 EVAP EMISSION SYSTEM VENT VALVE/SOLENOID CIRCUITP0452 EVAP PRESSURE SENSOR/SWITCH LOWP0463 FUEL LEVEL SENSOR A CIRCUIT HIGHP0308 ENGINE MISFIRE CYLINDER 8THANKS
  15. swapped the #8 plug with a brand new plug, and then swapped the #8 wire with the #2 wire but still misfiring
