86 Mazda engine dying. Sign In

i have a 1986 mazda b2000 truck with a 2.0 engine and 5 spd transmission with 146k mi. the problem im having is when i come to stop or slow down really slow the rpms go way lower than normal (~500)/engine will sometimes die on me. when i start out to work in the morning its not bad or doesnt happen, but it gets worse the longer i drive it like when it gets warmed up something goes wrong. a previous problem that i had was it wouldnt start at all but replacing the ignition switch fixed that problem. i thought it might be the fuel filter so i bought one but am currently unable to find it on the truck to replace it. any help would be appreciated.

thanks

You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

You know, I'm going to have to back up on that. Your engine is carbureted and I assumed it was fuel injected.

You may have something like a stuck EGR valve or just some internal carb problems. It's really going to have to be inspected.

Sure, just remove it and see if the pintle is fully seated. If it is, leave the vacuum hose off when you put it back on to see if anything changes.
