Stalling during idle and very low speeds.

[bdt115]

'99 explorer 4.0 SOHC automatic 4x4 almost 200,000 miles. I just bought it and love it so far...drives great...squeaks a decent amount on the front when i drive but great ride and pretty good power. It will idle at about...maybe 750-850 rpms for maybe 30 seconds right after i start it but any other time i idle itll be about 550-600 rpms..itll stall in any gear...drive, reverse, park. Ive already changed my air filter today so maybe 25 miles on that and cleaned the throttle body out best i could. Need help quick!

Could be a vacuum leak, check all of the rubber hoses that attach to the intake and pcv system, that's an easy first step. Welcome to the forum!

get a can of brake/parts cleaner and spray it all around you intake manifold and all your vacuum and connections while idling... if changes in rpm u might have a broken vacuum line...

Alright ill try that and let you know how it turns out. The cleaner wont hurt the engine any?

 

[tvalentino]

nope wont hurt... just some ol' regular brake parts cleaner

Brake cleaner is not a good idea-it does hurt plastic parts.

I'd clean or replace the IAC valve

it wont hurt plastic parts... on the other hand if u soak them in a bottle of cleaner it might melt the plastic but a quick spray around everything wont do anything and will evaporate quicker than u can find a puddle of the cleaner... its the oldest trick in the book to find a vacuum leak...

Welcome to this forum! I've moved your thread into the stock 95-01 section. Brake cleaner is flammable so use caution. It sounds like the IAC as previously suggested.
