Engine Mechanical problem
2004 Chevy Tahoe V8 Four Wheel Drive Automatic 72000 miles
I have a 2004 Chev Tahoe that is giving me nightmares. I recently had to have the heads replaced because one was cracked even though it had never overheated. The day I got it back, the engine light came on. We had the mechanic reset it, thinking maybe a sensor was jarred. Ran fine, we even drove to Texas and back (1600 miles). Engine light came back on but was running fine. Yesterday (about 6 weeks since heads replaced) it started dying down while I was idling at red lights. Oil pressure would drop slightly. Filled up with gas Monday, this was Thursday morning. We've had some minor flooding, thought maybe water in gas at station. Napa man said may be throttle plate needed to be cleaned. Took it in today (Friday) and there is a skip in cylinders 4 and 6, can't seem to figure out why. At my wit's end, please help.
