Hi I had to reregister under a different name because I can't find my old password and the password reset function isn't working for me. I've been a member for a few years I think I used 94_Mazda_4x4 as my UN.
In any case I have been having a rough jumpy idle for the past two months. This is a 94 B4000 4.0. I thought I had figured it out and i replaced the DPFE sensor, but the problem came back. Then my idler pulley fell off recenetly, and I thought I had found the answer there but a new pulley did nothing. My ac compressor just failed, but seems to spin freely as long as AC isn't on. I unpluggedthe compressor to ensure it doesn't try to kick on. Anyway, I'm not sure what to try next. The truck seems to run fine when I'm driving, it just won't idle smoothly. Any ideas? I keep seeing the MAF sensor come up in my searches. I don' want to spend money on parts unless I can pinpoint the prolem.
