SOURCE: My 1997 Isuzu bighorn (trooper) appears to "miss"

When is the last time a tune up was performed on the vehicle? I would get some amsoil engine foam, and use it as described. Also get some fuel system cleaner and use that as well and go from there.
Thank you,
Lee

What is causing the fast Idle and slowing down


well gee, there are 50 reasons.
did you scan the PCM yet, if not ,why not?
when the idle surges, that means.
NO RPM ranges stated, if super low rpm check EGR.

1: engine lean and ISC dead, or cant handle the huge engine power drop..The PCM can even make this worse!, buy hunting the ISC to find spec, idle and failing... to...
2: or any of 50 other things causing huge engine power drop and PCM can't maintain idle controls.
super lean burn.(bogging)
super rich burn, misfire for 50 reasons.

i cant hear your engine,nor feel it, or see it shake from gross misfiring.
no can i drive it and see/feel power loss,
can I?
asking net bunny's this (blind as bats)
is "OVER THE TOP" no?
so here , ill toss the dice for you
and guess gross misfiring.
ever get a tuneup this decade, if not bingo , no?

and the others...

link even has the 50 cause list, to show the futility of guessing!
we do 1 to 10 tests. and find it.
for sure.

as you can see EFI systems are complex.
gue$$ is not only expensive but can net you 2 problems easy.

Rpm's fluctuate at idle


The oil pressure quage is moving around because the engine is slowing down and speeding up. As far as the idle surging goes try this.

Motor runs a little rough, idle goes up and down


From my experience with my wife's 97 Wrangler look at the intake manifold for 2 vacuum lines. They will be just under the throttlebody One of them is broken or has come loose. We had this problem several times, idle high, running eratic, until I put a smaller rubber hose on the fitting. Has run good since.

Why would the rpm for my 1997 Nissan Maxima go down to 550 when the car is in the idle position? The RPM's of my car go down to 550 when the car is at a stop light.


I don't really know where they should be in idle on your car, but if you don't apply your gas pedal, the RPM's should be low. My 18 wheelers RPM's are down to 500 in idle position and go up to 2300 when I step on my "diesel" pedal. If in neutral or park and you step on the gas...do your RPM's go up? If yes, all should be okay.

Surges in RPM while at idle


It may be one of two things. A intermittent problem with the idle air control sensor or the throttle position sensor. Have the cars computer scanned at a local auto parts store to see if there is a pending code that has yet to turn on the check engine light.

97 Eclipse has bad idle, help?


This really sounds like a vaccum leak at the intake. Just spray a bit of starting fluid at the intake manifold, with the engine at idle. You will hear a change in the engine. Replace necessary gaskets.
