Engine Performance problem
1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic 175000 miles
I have a 98 chevy blazer. I have been scouring automotive repair websites and have seen many blazers running into this problem. When the truck is cold it hesitates badly sometimes almost to the point of stalling out it seems but never quite gets there. I just had a full tuneup and have taken it into the shop 2 times already and the mechanic cannot figure out whats going on. As soon as it warms up (About half an hour of driving) it runs great. I just had my fuel pressure checked and it read at 55. The weird thing is that the computer is not throwing any codes at all, had it scanned twice. Cleaned the maf sensor and that didnt work, also had the Idle air control valve cleaned but not replaced, thinking about the coolant temp sensor but Im not sure if thats it. Please can someone clear this up for me once and for all!
