ok so now that the fuel pressure issue has been resolved and i can actually adjust that now the car now runs leaner than b4... at idle im in the 18's to 19's then about every 45 secs the car will just cut out and shoots to mid 20's on the gauge...almost cuts off then slowly goes but down to the 18's and 19's again...

fuel pressure is set at 52psi at idle without vac line attached.

only codes for now are the mutiple misfire codes

before I fixed the fuel pressure there were TPS codes thrown...

Any ideas before I go out buying all these sensors for nothing???

One more thing...I unhook the MAP sensor and it goes pig rich....im guessing that is normal?????

 

can you say retune?

If you tuned it before with 85 psi of fuel pressure of course it is going to be lean now with 52

 

in all honesty I have no clue what it was tuned on as far as fuel pressure goes...and im sure that they did not tune it while the pressure was that high...but maybe im wrong?...My car was tuned by Sharif before CPRace closed down and the tune was perfect...

Dont think its my tune unless somehow the Utec got erased which isnt possible because its hardwired...meaning like you cant just unplug it and all settings disappear...i think..ill check to make sure

Gonna try cleaning that sensor with some electrical cleaner and see if that makes a difference also

 

Utec

 

I cleaned the MAF sensor and that stopped it from running all stupid...but still lean at WOT

and guess what...i cannot connect to the stupid Utec...grrrr Ive tried all different kinds of settings...the ones in the manual first and then others...with USB and the serial cable...nothing...I need to take it out and see if im actually getting power to it at all...sighs...i feel like a doctor
