Hey everyone! I just picked up a 92 Bronco XLT with a 5.0 with around 212K on the motor. The thing starts up, and idles smooth as silk. I checked compression, and pulled codes, and had it smoged. All seems well with the engine. It runs well once I get it up to cruising speeds. However, dead stop, and at times mid-range acceleration seems very sluggish. Now keep in mind the last ford (Mustang LX) I drove had a H.O 5.0 in it and that was many years ago, but the acceleration was much better, gas peddle was more responsive, and the mustang felt torquier than this Bronco. So the $1K question is what's up? Is this all I should expect from a 24 y/o Bronco? There are times that I can mash on the peddle at lower speeds and the tranny kicks down and I can get up and go. From a dead stop... not so much until around 3.500 RPM. There are other times when I mash the peddle and... trickle. no kick down, no get up and go. This happens at warm and cold engine temps. This may be unrelated, but I'll mention it anyway. It seems smelly, like fuel and exhaust. The down and up shifting of the A4OD seems jerky and a little unpredictable at times.
Okay so all that said: I haven't wrenched since I was a younger man, so my confidence has waned over the years. I'll be taking it in for a full work up at my local mechanics shop, but I'm curious if there's something in particular with 90's Broncos that I should be aware of. Vacuum issues, running too rich, timing out of whack, throttle body linkage? ECU? Any thoughts or advice are welcome.
I apologize if this has been covered before, I looked around and found a few similar but not exact threads. Thanks in advance folks!
