Good morning. I'm now in month 3 trying to get my '88 Bronco II running properly. Background: Found this XLT for sale, buried halfway up the wheels in the ground, had been sitting 4 years, half a tank of fuel remained. Amazingly it started and drove out of the hole with just a battery and aired up the tires. Had engine rebuilt (not reputable shop as it turns out), transmission rebuilt, headers and high flow catalytic and resonators... have replaced pretty much every part on the engine from alternator, A/C, TPI, coil, distributor, computer and more. I got it running but rough... tweaked for a month, took to local mechanic and he gave up. Took to a more reputable mechanic in Boyd, TX and he had it for two weeks while I was on a business trip. $400 later, swapped out my new parts for other new parts, have the same issue which goes something like this: starts fine, while cold: sounds good, idles great, drives normally through just above idle throttle. Also, runs smoothly when floored. Example. I accelerate to 55mph, set the cruise and it runs great until the first hill/load on the engine. It then misses and loses all power until the throttle is near full at which time it revs up, runs smoothly to 55 and then loses power again. If I leave it on cruise it goes from 55 to 45, loses power, then when full throttle accelerates back to 55 at which point it again loses all power... over and over. I don't think there are any parts not new! I'm wondering if there is a 2.9L expert in the North Texas region who I can take this too or if some of you have had a similar experience/aha on this.
