I have an '89 cavalier z24 with a 2.8l multiport engine. My problem is
when i push the throttle there is a gap before the engine takes its fuel. I
can hear the air being drawn but no rev for the first 1/2 second. once i
open throttle and hold it's fine, if I let go and rev repeatedly the engine
bogs slightly then revs on every attempt.
EGR valve works. I just put a new exhaust system and gave it an
electrical tune up (except o2 sensor which I'm going to try tomorrow), but
It still behaves the same.
I would love to hear any ideas that would save me some headache.
