Engine Mechanical problem
1997 GMC Jimmy 6 cyl Four Wheel Drive Automatic 151000 miles
I have a 1997 GCM Jimmy. Over the past 6 or so months I have had some trouble starting. The engine would crank but take some time to fire up, mostly after a second try or giving it some gas it would go. Three weeks ago when starting up it made a grinding noise similar to holding the key after then engine starts, but it still never failed to fire. My mechanic replaced the starter and now the noise is gone. Since that time I frequently have to hold the gas down to get the engine to fire and rev up, but if I let off the engine will die. I have to flutter the gas for 15-20 seconds reving it up and then it seems to idle normally. It has also come close to stalling a couple times at stop lights. The problem seems to happen starting a warm engine mostly but not exclusively. My battery measure 12.3 volts without the engine running so that seems ok. I plan on testing fuel pressure this week. Any other ideas would be great.
have the same problem?
