Question about 1988 GMC S-15
These all may be related, its having a hard time starting, its harder when its warm and it takes mabey a minute of cranking while pumping the gas to get it going. It idles fine, mabey a bit high but im not sure. But when im accelerating it pluses and looses power and when i press on the gas it starts sputtering and doesnt like to go much faster than like 50 in 5th gear. Which by the way took me like 15 minutes to accelerate from like 40 to 50. Ive had this problem before but it went away for like two weeks and decided to come back. I think it might be fuel pump related.
REplace the fuel filter, then check for vaccum leakes around the intake. My guess is the carb it close to falling off! LOL Frankster016
