Low idle problem can cause by a lot of components.


Dirty air filter

Dirty injectors + o-rings

Vacuum leak at intake manifold and vacuum hose.

Bad Idle Air Control Motor (IAC)

Low compression (170 psi + is OK)


Start cleaning and repair these trouble spots and see is there any improvement.


Please rate my answer if it's useful to you.


Cheers,

MUSTGO.

My 1999 troy lee b2500 will not ital


If it's really rough, check for dirty or stuck EGR. It just slightly rough and also you have to depress gas pedal a bit to start, check IAC (idle air motor). If gas mileage is also bad check coolant temp sensor.

Why is my 99 Ford Ranger dying when I step on the pedal?


Is the check engine light on when the engine is running ?
You'll have to figure out if it is a fuel problem or electrical problem.
Have you checked fuel pressure yet ?

My 99 malibu starts and dies right away. It won't stay on unless I keep the gas pedal down and rpm above 1500


the ( iac ) idle air control is sticking and needs cleaned. heres how to clean. locate it on the throttle body, remove wire connector, remove the torx screws that hold it on. when off of car. clean valve on end you can use a old toothbrush or similar to do this. do not push in on valve it will mess up idle setting. on the 3.1 the setting is 1 and 1/8 from tip of valve to body of iac. you can use gumout spray or throttlebody cleaner. here are a few symtoms-- stalls after starts, when cold or hot. stalling on deceleration, stalls at idle, unstable idle, low idle, or stuck on high idle. hope this helps !

I can start my 1998 mazda b2500 pickup truck but it will not shift into gear


The truck must be a standard trans? If you can shift it with the motor not running, but not with it running, then most likely the clutch master cyl must be low on brake fluid. It must have a leak. Sometimes you can add brake fluid, then pump the clutch pedal slowly and you might be ok. But you will need to get it repaired.

good luck
