I have an 89 Chevy 4x4 with a 350. The car sat for about 2 years in a garage. Last year it was given to me. I drove it home about 50 miles and it sat for another year. Its running rich but seems to run ok, only problem is when you rev it up, let off the gas it acts like its going to die then picks up again. I want to take it on a camping trip with my kids and get it through DEQ.
It has a set of new heads. I put in new plugs and wires last year. Any ideas? I'm thinking the Engine Temp Coontrol sensor and MAP sensor?
