It was assumed that vented opti was the whole deal, not an opti cap. If just the cap, would still work.... if it was an 93 opti it physically will not fill the 96 timing cover hole..... it would be pretty obvious something was wrong when installing it let alone trying to bolt it down.

 

Quoteing y'all quoting me ... OP?

 

I'm more curious as to how it got wired up. 96s came with MAF, sequential Fuel Injection, and a crank position sensor, whereas a 93 operates under speed-density and batch FI and thats it. thats just the basics. There has to be somehting wrong in the wiring.

 

^This.

 

Regarding the cam pin, Porter said he ground this down to fit, and the timing cover was switched. He claims he covered that issue. The intake from the '93 (which I think inside houses the sensors that speed density utilizes) was placed on the '93, the MAF isn't being used. PCM is being used from the '93 as well.

 

I mean the '93 intake was placed on the '96 motor. Sorry for the confusion.

 

Running the 93 PCM, the mechanical motor has no idea it isn't utilizing the CPS or MAF..... Come on everyone lets not get hung up on this, there is no problem running a OBD-II year range motor in a OBD-I range car......

I put a 96 Impala motor in a 94 Formula, no wiring problems.

 

Agreed, the actual motor doesn't have a clue.

 

What about plugs? You said wires were on correctly. Even if they are.... with bad plugs nothing is going to run right.

 

have you verified spark at each plug? didn't see it mentioned and its the easiest place to start if you haven't already. also triple check the spark plug wire routing

also what did you do about the fuel rail cross over since '93 intakes don't have one?

 

Were the injectors from the 93 used or the other motor?

 

The fuel rail and injectors were used from the '93 as well, and the plugs were new obviously.
