Hey everyone!

So heres a quick description of the car

95 GSR
JRSC tuned with Hondata @ 8psi
RC 440 Injectors
Walbro FP
200hp/ 144tq

And the problem...

A few days after the tune, I was driving and the CEL turned on. I immediately babied it home to find it idling rough in my driveway. When i checked the code it was CEL #3 (Map Sensor). I started the car again and the code went away and so did the bad idle.

I drove it around for about three days until i was on a 140 mile journey down to college, when the same thing happened again. I kept it outa boost just to get it down where i needed to go but the car was running super rich. The CEL turns off everytime i turn off the car, but whenever i try to start it, it idles rough and after about a 1/4 mile of driving the CEL turns back on.

AND IT RUNS REDICULOUSLY RICH.

Heres what ive done,

Replaced MAP Sensor with OEM Honda one.
Replaced the connector that the MAP sensor plugs into with one from a local junkyard.
Checked all soldering jobs i did when i installed the SC.

Anybody have any advice on what is going on?

Thanks so much

Kyle

I take it when you went with the hondata you eliminated the FMU and you moved your vacuum hose at you Map sensor so it sees boost. Iam not sure on yours but when I redid my CRX I eliminated the FMU took the empty vacuum bung and used it for the Map sensor, Removed my resistor patch cable from the kit and added the injectors and ECU. Maybe this helps maybe not I tried.

Thanks dave,

Yeah when i got my hondata, i removed the fmu and ran that vacume line to the map sensor, along with adding my RC 440's.

What is a resistor patch cable?

Thanks for the reply

daveb91

It was the cable that was used to extend the wires to the intake temp sensor. you might not have it.

nah i dont think so, i justed used regular wire from radio shack.

This thing has been tuned with a wideband correct?

debogsr

Yes sir

When you dynoed it did it also come with an A/F curve with it? Was it running rich with the dyno tune? A FI car is supposed to be on the rich side but not so much it will start fouling plugs.
