    EGR opens randomly - 92 Blazer K1500 5.7L TBI

    FYI: The truck ran perfectly when I bought it 1.5 years ago. 6-7 months after purchase, I started having issues. I've been having this annoying issue where seemingly at random, the EGR opens and wants to stall the vehicle. I have replaced both the EGR valve, and the EGR solenoid, but it still...

    Truck stalled for the first time at low mphs.

    Gents, my Tahoe stalled on me twice today while driving around 15-20mph which luckily it had never done before and it started right back up the first time. The second time it stalled today since the starter motor was heat soaked it wouldn't start back up for a few minutes until it cooled but...

    Stalling only on left hand turns?

    I have a 92 GMC Sierra and recently we had fixed the cab by fabricating a piece of metal to be in place of where the cab mount itself is supposed to sit because she’s rusty with trusty.. and ever since then when I turn left my truck stalls out I’ve replaced the throttle positioning sensor, idle...

    91 TBI 350 randomly dying

    91 c2500, 5.7 TBI, 214k miles. I've driven this truck around for months with no issues, suddenly one cold morning it started up fine but stuttered itself to death and never started again. No big deal, I figured. All the ignition components looked like hell so I threw plugs, wires, cap, coil, and...

    1990 C1500, Strange Stalling Issue

    Hey Everybody! First post but I have been lurking for a bit ever since I bought my truck a while back. I have a 1990 Silverado RCLB C1500, with the 350/5.7L & auto trans. For the most part it idles, drives, and starts up alright (or so it seems.) I get about 30psi of oil pressure at idle and...

    1994 gmc sierras 2500 5.7 tbi stalling/flooding.

    I've been working on my truck this last year and thought I got it running good but now I have it stalling randomly, with a gas smell. When it first started I could just start it up again and keep going down the road. Lately though I've had to leave my truck sitting for 20 mins before it will...

    93 GMC K1500 Code 45

    Hi everyone, I have a 1993 GMC K1500 I bought with 160k miles a little while back, and it has an issue I have been totally unable to fix. My mechanical knowledge is pretty limited, but I figured this would be a good car to learn on. When I first bought it, it would randomly stall at idle every...
