ok, i have codes 30 33 39, done a swap, cranked it, has rough idle, and wont rev above 3000, without cutting out, and the check engine light blinks on, but dont stay. the codes are coming from the acv, i think, and i have taken the UIM off, and found some unhooked harness's, and a broken metal nipple, that a vacuum hose hooks too, im just wondering if the could be the source or my problems? ive included pics,

thanks, any advice would be appreciated!

 

that harness should be left unplugged... map sensor ok? all wiring secured under UIM? All hoses secured under UIM?

 

thanks ejmack1

 

That light blue connector is the EGR connector for Cali-ECUed RX7s. If this needs to be plugged you would have received an EL code. Codes 30, 33 and 39 are ACV codes as I have explained before. The are not fatal codes..they will not put your ecu in LIMP (dick) mode. But nonetheless, they are an eyesore to have blinking on your dash. I have a PFC, so not necessary to have plugged in, but I still removed the solenoids from the ACV and connected them to the engine harness. Before installing my PFC, I checked with stock ecu to make sure all was good with the electrical. If, for whatever reason, I wanted to change back to the stock ecu, I would not have to go back into the harness.

Obviously, any broken nipples (tee-hee!) are a problem.

 

OK, I was wrong then about the ACV failure causing the limp mode (if that really IS his problem). Cover8, do you know where one can look to find out exactly which ECU failure signals DO cause limp mode? I know OMP and MAP sensor, but are there others?

 

I don't think the MAP sensor will cause limp mode, it will just run really rich.

Someone on here a while ago reported something similar to limp mode when he went non-seq and pulled out his solenoids without installing the appropriate resistors.

 

May wanna check section F in the manual page 20 or 40...think it classifies them there.
