I am reaching out to the Trailvoy community as I am not sure what to do next. I have a 2002 Tblazer that has a consistently rough, low idle, it hesitates when accelerating from a stop and almost stalls. The worst part is, I am getting about 350km to a 60L tank of fuel... I used to get almost...

I’m having some issue with my 04 xuv, I’ve replaced vvt solenoid, cam position sensor , iac, A/C delco spark plugs, coil packs, fuel filter and throttle body. All with ac delco parts. I’m at my wits end. It mainly does it while in reverse and turning the wheel it’ll stall most the time shutting...

Hey everyone. I have an 04 envoy xl slt that recently started acting up on me. It has been running good but the other day I started it and after 5 minutes of sitting in park in the driveway, it stalled. It will start but runs choppy, like it wants to stall. Also the check engine light just came...

Bought a used 2002 trailblazer that had some problems when I got it. Threw codes p0340 and p0014. Stalled out when breaking at random intervals. I replaced the camshaft actuator solenoid and camshaft position sensor, changed the oil, changed spark plugs and finally got it to pass emissions. Now...

Hi! My trailblazer has codes P0506, P0128, P0014. Main issues with it are it idles a bit rough/low. Sometimes I have to pump the gas to get the vehicle to start up. while I was driving the other day it all of a sudden just turned off? Hasn’t done it since. So far we’ve replaced the battery...

Let my oil get lower than I would like. 4.2 vortec in a 2008 GMC envoy. Sounds like rod berring knock and she drank 4 quarts plus honey. Drove it 3 miles and it stalled at every intersection. I also couldn't use drive, only 1,2,3 gears and then it would stall again slowing down/ stopping. I am...

This was an issue I put up with a few months ago (by put up with, I mean I quit using my left blinker for awhile ??‍♂️) The issue started again just this morning. When turning on the left blinker the dash starts beeping like WWIII, Service Brake System appears on the dash, the “Brake” and ABS...

I have an 04 trailblazer with the 4.2l, giving me absolute fits. For some reason, it randomly stalls at stop lights when the A/c or heat is all the way on. it usually acts like a slow stall, the RPMs drop way low, then quits, but then it starts right back up after i put it in neutral or park...

It made me put solved up there? Not sure if that's correct. I have a 2002 GMC Envoy with a 4.2L motor with 143K on it. I recently started to smell gas coming from the right rear side of the truck, so I assumed it was the fuel filter. Then when I would come to a stop sign it'd feel like it was...

Hello All, I bought my '03 Envoy SLE 4.2 I6 a few months ago and drove it over 1000 miles until one day it stalled on the road. It would start back up but then stall right away after 1 or 2 seconds. Of course CEL and no codes. The things I've looked at or done so far: Checked all fuses (both...

I have read many forums here, and nothing seems to help me, I have replaced the thermostat, ECT sensor, camshaft sensor, crankshaft sensor, fuel pump, and cleaned the throttle body. I am still stalling out once the engine is warm and I come to a stop. I am still having the same codes reading...

OK, My 04 4.2L trailblazer has been stalling at Idle while stopped at a light Occasionally. I recently had it to the local GM Dealer and they recommended a fuel system cleaning, from the Fuel Rail, for which I have ordered parts for but haven’t come in yet. However the tech said that he had...

I am thankful for all the folks in this forum, I have solved a few of my issues already and I am hoping with your help I can solve these last problems. Symptoms: It does not seem to matter cold or warm start, when I slightly press the gas pedal sometimes the engine will slightly stall then...

Hey guys, my 02 Trailblazer 4x4 I6 keeps stalling at idle and low speeds, especially with AC on. SOmetimes I have to hold brake and give it gas to keep it from dying, then sometimes it runs just fine. It has about 160k miles on her. There were no codes. I have taken the throttle body off and...

Ok, so yesterday I was waiting in line to pick up my daughter from school, had driven my '02 Envoy for about an hour previous with no problems, and out of the blue it starts coughing and sputtering, and eventually dies. Low Oil Pressure flashes. I start it up again, and for the duration of...

Need suggestions! I have cleaned throttle body and replaced camshaft sensor (it was throwing out code p0340) but it still shudders and stalls out, especially when braking or accelerating from a dead stop. Is the throttle body bad? Suggestions needed. I also reset the computer after cleaning the...

Hi, I have a 2004 Envoy 6 cyl. Every so often when I'm idling and a stop with the AC on the engine stalls. It starts right back up and everything is fine for a while. The engine also seems to be "bogged down" on these hot, humid days as well. I had it to a dealership 2 weeks ago and they...
