  1. Bad Spark

    I have a 1987 Bronco II. I am not a mechanic. I replaced the TFI Module. I Screwed something up. I was getting some slight hesitation when I pressed the gas, the idle was a little rough, and a little rough on start up and going from drive to park. I figured the ignition system. I checked the...

    Is the 2.9 SEFI, MFI or just regular EFI? OBDi Cylinder Balance test

    Hey there, I want to perform a cylinder balance test with my Innova OBDi reader but am not sure if the 1990 2.9 is SEFI or not. It says in the manual it's only for SEFI so I don't know whether I can perform this test or not. Please let me know if there's a way to do this test if it isn't. Thank...

    Bii always running cold

    I have a 90 Bii that never goes above the "o" on normal. The ECT and temp switch to gauge have been replaced, the latter i assume is what fixed the old issue of having no gauge reading at all. There is a 180 thermostat installed which I know would make it run cooler but idk about that much...

    AC/Heater keeps blowing cold/hot air when ac is turned off and car is running

    I can't figure out why, but my ac/heater blows air when it's fully in the off position. It does not do this when the car is off but when I'm driving and get too warm I turn off the heater like anyone else but the darn thing keeps blowing even though it's slight. But it's slight enough to keep...

    Poor Acceleration Fixed - Bucking, jerking, etc… Fuel Pump!

    BLUF: In-tank low pressure fuel pump/ sending unit caused no acceleration beyond light touch on the gas. Figured I’d post here because I’ve seen a few threads with no final updates of 2.9l owners having identical issues, but disappearing without a final update (perhaps after having fixed… or...
  9. Neutral safety switch location

    I ran the paperclip method for my 1992 Ford ranger 2.9l automatic engine and got a code of 67; which is the neutral safety switch, but I can't find it on the truck. Please help! I realized that I didn't touch the brake will doing the KOEO test either, could that be the problem?

    Need a diagnosis! Pulleys, belts, or transmission?

    My 2.9L with an A4LD has begun making this noise at around 4000 RPMs, but once I drop below or gain about 500 RPMs the noise goes away. What gives? Sorry for posting twice in such a short time frame, just trying to get as much information as possible.
  11. Rough 2.9l

    I picked up a 1990 XLT with 4x4 that had been sitting outside for about 4 years not running. Gone through and replaced gas, fuel pump, filter, oil, plugs, injectors, IAC and MAP.... Still idling at around 1200 and kind of bogs a bit on 1st gear and barely gets enough power in 4th and 5th.. Not...
