Shakes or Wobbles problem
1999 Chevy Tahoe V8 Four Wheel Drive Automatic 115000 miles
I was coming off a bridge and when I fully stopped, the truck started lurching violently forward and even a bit of side-to-side. The "check engine" light flashed rapidly on and off before it stalled. I was able to restart it, the "check engine" light steady this time.
Whenever I'm idling at ~500 RPMs, the truck starts lurching again; above 1500 RPMs, it's as if there's no problem at all.
Oil pressure is fine, the battery is new, the engine isn't overheating, and there's no smell from under the hood. My computer is telling me the #4 cylinder is in need of maitenance, but a compression test is showing me it's not a broken valve. The spark plugs have been replaced, so I'm wondering what else it might be. Someone recommended it might be a "spider injector" problem. If this is the case, what kind of expense am I looking at to replace it? Is this even a valid diagnosis?
have the same problem?
