Question fellas And ladies, I typically don't post on forums, but I'm at a poss currently. My truck is 2010 Silverado 4.8 and after driving it for 30 or so minutes the traction control/ stabitrax light comes on, the tachometer cuts off and the truck feels like it's jerking going forward, if I'm stopping or stopped the truck stalls and won't turn back on for Maybe an hour. I've replaced the fuel pump, crankshaft position sensor, engine temperature sensor, replaced the plugs and wires maybe a year ago, and I don't drive it much because I live close to work. Yesterday I had been driving it a little farther because I thought it was fixed, but as I was getting on the highway, the truck popped/ jerked, and the stabitrax/traction control off displayed and a couple of seconds later, the tachometer went to zero. I was able to get her home, but the truck kept jerking all the way home. I think the problem is unrelated, but my oil pressure has been getting lower as I drive it. Any help would be great, thanks.

So I ride a 18 Sierra 1500 with the 5.3L and keep getting gas in my oil, my high pressure fuel pump let go in March of 2019 (40000kms ish) and was the first time I got gas in the oil, they replaced it and it was good until late December of 2019, I drove 800 kms to home, parked at the restaurant and went to go home and got a bunch of codes, saying that bank was to lean, bank 1 to rich, bank 2 to lean, bank 2 to rich and a open circuit fault code. The truck was in limp mode but got it to the dealership, they found a short to a relay for the hp fuel pump and my crank case filled with gas (same as the last time but now the truck at 69000kms) they tested the O2’s, fuel injectors, injector cycles and such, they all passed the test so they figured the hp fuel pump went, so they replaced it. I then drove not even 3000kms and my truck was doing 33L/100kms downhill at 104km/h, no codes or engine lights. Checked the oil and it was over filled and smelled of gas, brought into the dealership and they said the Intake tube after the MAF was loose causing the engine to over fuel, now not even 2000kms (3 weeks) into the dealership “fixing” the issue, my oil is over filled and smells strong like gasoline. Any ideas on what the issue could be? I don’t want to keep paying for an oil change every 2-3000kms and 100$ deductible for my extended warranty. I know it’s not healthy for the engine and GM Canada won’t do anything about it.. Any ideas as to what the issue might be would be awesome, thanks

I have a 1999 Chevy Express conversion van. It has very low miles on it. It has the Winnebago conversion package from Chattanooga, TN. It was supposed to have the 34 gallon tank per the conversion documents but only has the 31 gallon tank. I would like to add a secondary tank where the spare tire is located under the body and behind the rear axle. Has anyone found a company that makes such a tank? If so, can you provide me with the link? Thanks!
So I have a 2018 Silverado 5.3 Z71 LT and I've tried looking up threads for this topic before but for some reason I haven't had any luck. Ive had this truck for a year now and I had a level lift installed and my MPG stayed around 18-22 MPG and I could get 325-400 miles out of a full tank of fuel. I recently installed a 3.5 Rough Country suspension lift and I installed 20" wheels with 33" tires. I knew going into this modification that I would see a slight decrease in MPG but immediately after the install I dropped my MPG to 7.5-9 MPG and I cannot get it to increase AT ALL. I used to work at a GM dealership and spoke to a couple of old co-workers about this issue and for some reason we cannot pinpoint the issue. I know that increasing the ride height and the different wheel/tire package would create a difference but I didn't know that it would be this bad. I'm considering a performance chip and a CAI to try and increase my MPG, and its not a bad batch of gasoline and I've changed my driving habits and kept my foot off the throttle a little bit...if anyone has any info on this it would be greatly appreciated, thanks a lot!!
