Guys, need some help here. Have a 2003 cobra vert that has given me a couple of problems that we can’t seem to figure out so looking for some guidance. The first issue is that I cannot get the car to finish the system ready procedure so that I can complete an emissions test. In the two years I have owned it, I just stays in system not ready mode. Will list the mods below but the car has stock manifolds a bassani catted x-pipe, EGR etc.
Secondly, since the day I bought the car, there are times when you are getting into the boost that the car will just fall flat on its face for a second or two and then pick back up again.
Recently in order to help with eth system not ready error I replaced the EGR valve thinking that maybe it was stuck. After replacing the EGR I found the car to be drive remarkably better, more power, smother etc. then during one of the times I was getting on the car, it cut out again. That caused a check engine light with the code P0174 – System Too Lean (Bank 2). I had never gotten this error before.
Mods
1st gen 2.3L Whipple with 3.0” pulley
60# injectors
JLT High Boost CAI
SCT 3000 MAF
Single blade accufab TB (I believe)
New NGK plugs
Chiller Killer
Black 306 modified FPDM with power wire upgrade
Dual Deutchworks 340lph fuel pumps
PPRV delete
Not sure if I am forgetting something.
My mechanic (who isn’t an expert with mustangs or cobras) has been fiddling with it and trying to datalog and believes it’s a fuel related issue. He’s had the tank down flow tested everything and on that end everything looks fine. He initially thought it was an MAF issue so had me replace the MAF. I replaced with a SCT 2600 as I don’t have any aspirations about making more power. Now he is fixated on the MAP sensor as he is convinced that it is being pegged being only a 2 bar and the car currently running 17#.
I did have the car dyno tuned last year but the tuner thought the car was missing at high RPM and shut the car down. He checked plugs etc and also thought it was fuel related. At the time i was running stock pumps and BAP which i then replaced with the upgraded pumps, upgraded FPDM, PPRV delete and a new fuel filter.
I have never heard of this issue before and tried searching on the sight but can’t find much info. I originally thought it may be an injector, but he doesn’t think so as we would be getting a different error code.
Any help, guidance assistance would be appreciated.
I didn’t build the car. Bought it as is and have been trying to work out the gremlins ever since. Car has ~82k miles.
Last thing, I am getting the dreaded battery light flicker from time to time, comes on for a minute or two and then comes off.
