Well this is about my 1985 Ford Ranger with a 5 spd/2.3FI..
*Got my trucked time by a mechanic (but he didn't use a timing light) but my truck ran great....
I was driving along and put it in 4th to go around everyone....climbed up to 65mph (truck is out of alignment bad so there was alot of shaking). Well I was fixing to pass the last truck by me and my truck started making a weird noise a little. Anyways, to put it short.....I thought I smelled oil or something (may be the brake fluid thats leaking some from my master cylinder) but my oil psi looked like it was reading good but my truck started to lose power. I put it in 5th gear to go along it just seemed like it just wanted to slow on down more so I put it in 4th and it would go some but you could tell there was something wrong.
Here are some videos of how my exhaust is sounding and one is a video of me driving (in 4th and 5th) with the throttle all the way down and my speed just stays and won't go faster
