1995 Cherokee with 4.0 engine. Intermittently, it
all that an not one RPM stated, making the meter useless.
numbers matter, tell them.
all that can be condensed to idle controls, dead hot.
you took it to a shop but was running great then.
so he guessed, and spent a fortune doing nothing.
why do that. ?
take it in broken, or have them drive it for a day to work.
find a real shop that can do that. and win.,
THE idle controls can fail many a way.
1: the control is bad. (ISC/IAC) they like to stick clean it.
2: vacuum leaks causing above.
3: gross engine misfiring (50 causes)
4: not scanning it. you didnt. so, work blind.
next time post actual RPM, when missing up.
and win, !!!!
the PCM not stuck in LIMP-in mode, will work big time hard
to prevent engines from stalling and to hold spec rpm
the ECU modulates the ISC to hold 700 rpm , HOT, in neutral or DRIVE, if you go P N, D and P, the rpm must hold at spec, 700
if not the ECU is not regulating RPM is it.
and not scanning it now, you may never lean why.
scan cars failing, not working right., and win.
lets say you said, just to show how important numbers are.
RPM is 400 or 500 engine shakes.
EGR stuck open( if it has one,)
or engine gross misfiring ever get a full tuneup this decade, even spark plugs. OMG no>?
injectors leaking or clogged
at the 10min no start.
does 5-10% throttle action (right foot) allow it to start now.
NO, try wide open throttle starts.
bingo, then its flooded
if it floods, post , why does my engine flood. and get other answers
like a tuneup.,
