Well today i put a new opti in and replaced plugs and wires again. to say the least i still have the problem. while the plugs were out we did a compression tes and the numbers came up 190, 190, 190, 210,200, 185, 190, 190. with that being ok. i started tracing wires to see if there were any brooken/frayed/damaged wires. Guess what i found 1 that was broken. it was a black wire on the drivers side just above the opti where there are 2 white wires that are grounded to the block. so i fixed that and i also replaced the ground strap thats in the same spot with some 8gauge power wire. and i replaced the rest of the grounds with the 8 gauge power wire. i then took it for a drive and to my dissapointment it was still stuttering/shaking. So with a new opti, plugs , wires, grounds, i decided to check the injectors to see if they were firing. I did this with a noid light. all of them are firing throughout the rpm range. so i checked the fuel ressure and with the vacume line pluged up its at 37 psi and with it unplugged its at 43 psi. so that was fine. I then checked the tranny fluid and it was dark brown with some matter floting in it. so i have came to the conclusion that it is the tranny causing the stuttering/shaking. but what makes no sense to me is why would it not let me go over 3k rpm under a load. if the clutch packs are shot then wouldnt it slip instead of bogging the motor?

Edit: the new grounds fixed the fluxuating voltage.

 

Ttt.

 

Sounds like you need some scan data for diagnosis. I would not think transmission, based on your statements.

Notice how no one attempted to help because you put my name in the subject? That just hurts your odds of getting more suggestions. I don't always have time or don't see every thread. Plus, there are plenty of good thinkers out there to help you.

 

I see you have a descreened maf. Maybe ya wanna see if someone near you has a stock untouched one and swap them for a few mins. Maybe the MAF is bad or dirty

 

hey shoebox,
I just noticed your join date is dec 1969, whats up with that? just wondering

Something that came from a board update a long time ago. Some ppl had join dates that could not be reconciled, so they made up a date. There is an explanation in the FAQ somewhere (but not much more than what I said).

 

can you give me a list of things i need to look for when i do a scan.
