    I was so sore after that repairathon, I woke up every time I moved last night.

    It wasn't until I started putting the trim/cover pieces back on that it finally dawned on me that the track was backward. Something that's not possible on the '90+ stuff (both of my '91s) I've been working on the past 7 years.

    Replaced coil, plugs, wires, spark plugs, dizzy. Made sure plug wires are away from one another due to crossfire. Under load at 25 to 35, hesitation and loss of power throughout acceleration. I have twisted my dizzy every flipping way in small increments, issue does not go away. Advice?

    You have a timing light? I think you said you did, or I would be surprised if you neighbor doesn't. Check timing and also double check for loose connections. After changing plugs and wires once I didn't get one of my wires seated all the way on the plug or dizzy cap and had an intermittent miss. Didn't take long to find and fix.

    Set the timing correctly first. Does the timing mark dance? Ever check the timing chain for slop? You can do this by removing the distributor cap and rocking the crank with a breaker bar. If the crank moves without the rotor, the chain is sloppy. 87's for some reason often got the shitty plastic chain, and the engine will not run right if the chain is loose. Also if it jumps the valves in the head bend.


    If its still doing it, unhook the EGR valve and see what you get.

    Thanks for the advice gentleman. Will definitely check the timing chain as well....if that is questionable it will give me an extra reason to strip her down to the lower block.
