thats why i asked. the blocks and heads are all the same 99% of the obd 2 junk hangs off the manifolds.



if you are touching the throttle and its sputtering or sounds like its going to die i think id be chasing a vacuum leak first, then if my TPS was adjusted right. proper voltage at closed, wide open etc. and thirdly id check the MAF sensor voltages. Id also assume nothing is correct until i prove that it is. not that i dont trust dad but, ya know



id also double check my piston 1 at TDC against where my dist rotor is. id even get one of those old school piston-stops that muscle car builders use to ensure the slug is at TDC. or just peer into the spark plug hole i guess.

Probably at least as bad as a Jeep so worse than a cow.

how do you use a ziptie as a piston stop? a piston stop is that thing that scews into the spark plug hole and is literally something the piston butts up against.

You put the zip tie in the spark plug hole and watch the zip tie move up with the piston so you can see when it's at TDC.

Solid advice. Might help to make a checklist and work through each system according to the FSM. If you can get your hands on a smoke machine to locate vacuum leaks that might be better than trying to spray fluid everywhere. You can DIY one, just check youtube. And speaking of youtube, you can upload your video there in order to share it.

Speaking of you tube look up a DIY smoke machine for a car. there are several variations to decide from. You can buy a DIY one on Ebay or Amazon as well.
I have xeen them made with PVC pipe or new empty paint cans.
Just curious have you has resalution? If so where was the problem and the fix.
