low power at light to mid throttle
I have a 98 gmc Sonoma with the 4.3 VIN w. It has 100000miles and is and auto. My problem is it has very poor performance at times. It accelerates slowly from stop to about 40 on light to mid throttle if you floor it it runs fine. It seems to run first gear out longer before shifting like if you were towing. Some times it will run great and other times it just falls on its face. Here is a list of what I have done. no codes
