restricted performance xk8
i have a question, i am working on a 2000 XKR convertible, i originally had codes p0300,p0301-308, p1316, p1000 and i RESTRICTED PERFORMANCE LIGHT. so i read changing out all the coils, so i spent 1000+ on 8 new coils and plugs. now RESTRICTED PERFORMANCE is intermittent ive checked the MAF, my STFT is weird when nothing on the dash is reads ok but when RESTRICTED PERFORMANCE comes on it goes to 0.0 flat, no ups or downs and if im at a stop and the RP light comes on STFT goes to -25%!!!! what does all this mean help me please lol, thanks

One thing to check is the intercooler aux. coolant pump. Check the fuse on the pump circuit ---it's located in the engine compartment on the passenger side near the firewall. I don't remember the fuse # but you can find it in the owners manual. I would get RP on occasion because my I/C pump wasn't working.

-25% is enriching the fuel to compensate for the extra un-metered air getting in.
