Engine Performance problem
1998 Chevy Silverado V8 Four Wheel Drive Automatic 204877 miles
I have a 1998 chevy K1500 with 204,489 miles. The transmission has been replaced and supposnly has 70,000 miles on it. I replaced the engine and it supposnly has 73,000 miles. My problem is when I first start it will miss and loose about 250 RPM and misses really bad on slow acceleration but sometimes will stop after 20 or 30 minutes. It also misses to begin with right before it shifts. If you accelerate really hard (Fast) it will not miss. When I changed the egr and took the battery off for a few minutes it stoped but started 5 minutes later. I also changed the MAP sensor and it stoped for a little bit but started agein.
have the same problem?
