ok ive had issues with this thing since I dropped it in. I had a high idle, vacumn leak, bad plug wires, header leak, and still have a weird miss. It runs great now at idle after I replaced the intake gaskets. It seems somebody must have checked into the motor before i got it and took off the intake. The last 4 bolts or so in the back were about hand tight!
Well after idle if I rev it it wants to die. If I got higher itll backfire into the intake i think. i have a optispark coming in tommorrow on a warranty trade so Itll cost me nuttin thank god! I replaced the Idle Air Control Valve cuz it was stuck open when I cleaned out the TB. I made sure about 5 times that the spark plugs are all in order, what else could it be?

 

would it help if I said it is a 94 LT-1? somebody has got to know. All these views and nuttin yet! Please help Im tired of throwing money at my daily driver that hasnt run daily in 7 weeks . The money is running out and so is my patience!

 

I forget how fast this site moves for the responses!

 

check your MAF

 

I swapped it already with one from a good running 94 Trans Am and also did the computer from the same car. It ran way better with the other computer but still missed. As soon as I get it going im going to reprogram it with the setup from MadZ28, or Ion

 

OPTI ???? if you did the plug wires and plugs.. Not sure if you did the coil or not.. might wanna look into that.. otherwise i'm betting on the opti..

 

optispark, the LT-1s distributor in the front behind the water pump.The crappy system. but Ill bet you know that already. I did new plugs, MSD wires, the coil about made me go sterile on accident! Dam that hurts!

 

yep.. That'd be the one!!!

 

anybody else with help on this?

 

should I mention that I only have one knock sensor due to the motor swap and that the other one is mounted a little away from the motor on the pass. side on a 45 degree angle piece so it could clear the motor mounts

 

btw the painless harness calls for only one knock, is this ok? could my one knock sensor be doing this?

 

would a header leak right next to the knock sensor cause this?

 

You would have to scan it and see if you are getting false knock.
Your miss is probably the opti.

 

we tried a scanner, a good one, and it said it couldnt read from the computer! weird. I might try to swap it to another one I got sitting around after I do the header leak tommorrow

 

the scanner we used was a Pathfinder
