the car starts everytime but it wont rev past 4-41/2 rpm and the throttle body sounds like crap when i give it gas. i am using pr4 5 speed ecu. ecu has no codes

check your firing order.. might help

 

You did have your wiring harness converted to Multi Port Fuel Injection right??? if your car was throttle bodied before, you need to send your harness to Hasport to have them convert it for you... if you did this already, double check the wires that you had to run to the ecu... they may be backwards... good luck

 

LOL. Outdated information. Harnesses need to be sent to me to be converted, not to them.


HF harness in 88 SI. Is the HF harness 88 as well? Cause if it wasn't, I don't think it would have been able to plug into an 88 SI main harness by the driverside shock tower. You should have also had one connector left over disconnected - a 3-wire connector by distributor.

Anyways, check this: by the passenger side shock tower.
Look at the 6-pin connector. One of the wires on the car harness side should be straight up white. The matching wire on the engine harness side, is quite likely to be Yello with white stripe. If it is, there is your plroblem.

Now, if it is so, try this: The plug on the HF harness, on the driver side, should have a white wire in it, somewhere. Take that wire, and extend it all across the engine bay to connect it to the white wire on the plug I was talking before.

I never seen an 88 HF harness, but if the HF harness is 89-91, then it should work.

See how the car revs now. Let us know how it went.

firing order is correct.

 

did you try what I told you?
