Engine Performance problem
1994 Chevy Blazer V8 Four Wheel Drive Manual 203000 miles
Hi! I have a 1994 FULL SIZE CHEVY BLAZER 5.7/350 and 2 weeks ago I startered in the morning for work with no problem, warm it up and drive it. After 3 mins of driving the truck started to idle rough so I step on the gas and went back to normal for another minute and then once again the fail. The truck finally shutted off, I took a look at the engine for some lose wire or anything weird. Everything appear to be fine so I started again and it runs fine but when it warmed up the problem was back. I tough it was the ignition module so I replaced bud the fail still there. I just did the entire tune up 2 months ago. I went to a garage and they could not find the problem because the truck it was rinning fine. Two weeks later (today) the problem is back the same thing idle rough but just did it for 5 mins and went back to normal. I drove it back home an did not have any problem. Do you think it should be a problem like the egr, egr solenoid or iac valve. Thanks.
have the same problem?
