  1. Greetings all. I have a1992 g3500 5.7. At idle and steady rpm she runs ok but has slight misfires not any one cylinder kinda like popcorn popping . Could it be a dripping injector (tbi)? 61000 miles. Fresh fuel . Good tune up. Whats the best way to see tbi spray pattern?
  2. When traffic light turns green, I kicked the throttle pedal, finally, this time, I got the power that a 454 supposed to give me, I almost cried. ======= 1994 Chevy Suburban Silverado K2500 454 L19 TBI 4L80E 153K miles ======= Months ago, I posted several topic (2 or 3) about it stall and knock sound under the floor, while cruising on highway. Well, the "highway" include GGB (Golden Gate Bridge).? 94' 454 stall while driving and knock sound under the cab 94'454 stall again, after change fuel pump Take note that I am actually
  3. I have a 1993 k3500 454 NV4500... The engine is a semi fresh rebuild(50K miles) with a small cam. I have replaced the following some parts multiple times... The truck has a stumbling rough idle. Seems to lack power to me but im not sure. If i take the truck for a short drive when i come back and go to instantly restart it has no fire from injectors....hit it with a little ether and shes up and running again. Im fairly positive i have that narrowed down to a weak oil pressure sensor.(changing it tomorrow). The truck runs pig rich and never seems to go into Open loop.(i think heated 02 will cha
  4. Hey guys, I'm new to this forum and new to owning my first chevy truck (with a small problem - hopefully!) and I wanted to post this here for some help/advice/guidance. I have done some research on this problem and only found one other post on the internet with this problem so it seems like a rare one! Unfortunately, the post I found died once the OP stopped responding. So here is the story and the problem:. As of yesterday, I am the new owner of my first Chevy truck! It's a: 1989 GMC Sierra 2500 with a TBI 350 It's completely stock and run
  5. This is my 1995 GMC Sierra SLE, running at 142,000 miles. Bought it used at a small business dealership for $6500.
  6. My good friend, who I help keep running, has a 1993 C2500HD- the one w/ the TBI fuel injection on a 5,7L block & the Eight Bolt 2WD hubs/rims. It's been running ok for a long time w/ more than 430K miles, mostly freeway, on the OD. It does though have a few nagging issues, one of which is the tachometer bounces up and down erratically while the motor is running. It's most pronounce when the RPMs are low, like around 1K-2.5K, but never really goes away. The truck also has trouble sometimes pulling up-grade without getting some pinging from the
  7. Im experiencing what seems to be vapor lock on my 94' yukon 350. It only happens when i try to start it after it has heated up a lot, during which time, it sputters and dies. It runs fine after holding a rev(around 2500 rpm) for 20-30 seconds. This is exactly what a carb filled with boiling gas does, until you burn all the hot fuel. When it does it really bad, i can hear hissing from the gas cap, which is a new gas cap. This is my first fuel injected truck, so im not sure how the fuel system works on this, but i would assume that its a clogged line going to the vapor canister, or possibly a ba
  8. Hello everyone, new member here from Tucson. I recently purchased a Yukon, and i suspect a bad alternator, but i am new to TBI so this may be normal behavior. When cold, im pulling a solid 14v, as the truck warms up, the voltage drops to 12v. With lights and a/c running its 11v, and it seems to have nothing to do with rpm. The truck has a new 600/750 CCA battery. Is this normal behavior for a 350 TBI? Thank you.
  9. Hi everyone I hope someone from this site will be more helpful than the last site I tried using. Ok here is what I got 1992 k1500 blazer with tbi 350. My question is if this motor can be changed from flat tappet to roller or am I better off to buy a new crate long block L31 vortec 350? (if I can use roller cam I'll put new 906 vortec heads on it) I'd like to run a lt4 cam or something of that range.is like to build it up and get 300rwhp. It has true duals already. I've been thinking of changing the 2 barrel tbi over to the 4 barrel efi unit with self tuning if need be. And I will not do an ls
  10. 2006 2500hd 6.0 put in new plugs, wires ,crank pos sensor,cleaned throttle body,MAF ...started up running good..went to go for a drive .plugged in scannner to erase cel and it started idleing rough...cleared codes ,engine died instantly..now it wont start...cranks but wont start...please HELP..Where do i even start?
  11. I have a 95 GMC K2500 5 speed with the 350 TBI and manual Tcase which I believe is the NP241 and the 5 speed I know is an NV4500. I don't think it's got the granny gear but I don't know for sure. It also has a 3.73 Posi. Good running truck for me, but you can't get much power out of a tbi. So before I dump money in it, I want others opinions for what's best. I am selling my '91 Corvette and using that money for my truck. I am wondering what you guys think is the best swap out there without having to do too much work, and being able to retain my current trans, tcase etc. I don't have the funds
  12. Truck shuts off as soon as i put it in gear and after initial start-up. I've bought a new IAC and cleaned throttle body and replaced the gasket. Any ideas to what else i can check out to fix this problem?
  13. Hey everyone, I am having issues with my 92 c1500 5.7l. I made this account because I desperately need help from people who know more about these things than I do. So let's start. The first thing you need to know is that I have a weird truck. Someone who had it before me said they had the CTS (cooling temperature sensor) go bad, and the temperature gauge doesn't work. Their fix for it? They hooked a manual toggle switch up to the ECU so that they can flip the switch on when the engine is cold, dumping more fuel, and flip the switch off when the engine warms up, giving it a leaner air/f
  14. I have a 1994 GMC Yukon 350 TBI 4WD that has a significant lope to the point of stalling, especially when in gear. When in park it will lope between 800 to 1000 rpms and when in gear sitting still will lope between 200 and 700 rpms and every so often, stall out. You can feel an intermittant stumble when actually driving although tach doesn't show it then. The stall will also occur sometimes when coming to a stop. The motor has plenty of power. Changed almost all sensors/components - see below for list of replaced items. I can temporarily fix the issue if I unplug the Coolant Temp Sensor t
  15. I have a 1989 k2500 5.7 tbi with 171,xxx miles on it. I've had no issues with it until a month ago when the engine is under load it cuts out, as soon as I let off it back fires and everything is normal. I've replaced cap and rotor, plugs and wires, coil, egr valve and solenoid, map sensor, tps and fuel filter trying to track down the culprit. Ran the codes, it came back with code 34 map sensor. Unsure why, cleared the codes and it throws it again. The truck idles just fine just won't drive well. I should probably also include that the truck has no cat anymore and is 3" straight pipped back
