1996 GMC Sonoma engine problems

Filed May 11, 2004 · Engine · GA

My engine has been surging, slow start, rattling, rough idle, hard shifting, and I have had the trasmission replaced 3 times. My dealer told me after an inspection that there was nothing wrong, but it was under warranty at the time. Go figure! I have proof of the new trasmissions. Now the compressor is cracked, and it will not hold coolant, and I can hardly get the truck going after sitting all night. These repairs are costing alot of money, and I am still paying for this truck. It is not worth the cost of repairs.

My timing tensioner keeps wearing out after about 15,000 miles, it started when I bought my truck in 96 around 25,000 miles I notice a ticking sound coming from the engine,I took the truck is to the service dept. They told me I was using the wrong oil filter,ha ha. They did something to the truck but the ticking stop until 36,000 miles and then my warranty was gone. I have replaced the timing chain tensioner 7 times since I bought the truck. I have had nothing but problem with this truck ever since my warranty had expired,the tensioner broke one time when I was on the highway,bent two valves,and a head job later still having problems. To me it looks like I may have bought a lemon. This may not be on all trucks but it sure has happen to mine. Its like the timing system does not line up. To wear the tensioner in such a short time. I have replaced with gm parts.

Noticed smell for long time. Started to try and fix 7 months ago, 11/17. Filling leaking coolant, noticing fluxuations in engine temp. Changed thermostat. Received notification letter(specifically stating not recall campaign) from gmc postmarked 5/30/00 of this problem. Dealer conflict on fixing this for me. Concerned about combustion and my family's safety.

The vehicle would stall out in middle of road. Its an intermittent problem, and it happens only in cold weather. Speed does not come into it. The mechanic, at dealership, could not find cause of stalling.
