I have a 1990 Dodge Daytona, 2.5 with 16v 2.4 stratus head and intake. I am running a a GT35R turbo set at a max of 15 psi
. This is a 5 speed manual trans car. The motor has about 400 miles on a fresh rebuild. This is the second motor of this setup in this car. I spun a bearing on the first motor after about 25,000 miles.
About 150 miles ago I fried my sbec
(fwd stage 5 cal) and swithed out to my original stock computer. I ran this computer on the original motor while waiting for the fwd sbec
and had no issues.
With the stock computer i am running way rich. i can kill a set of plugs within 25-30 miles. I have put the stock injectors back in, i put in a stock map
sensor, a new o2 sensor, i have checked the tps
and it is good. My fuel pressure is 55 psi
at idle. i even went back to the stock fuel pressure regulator. Hep
sensor is good and timing is set at 12 degrees. Cam timing is set at the stock 2.4 setting and it does have the stock 2.4 cams.
This motor ran great with this exact same setup before and i am out of ideas as to what is causing it to run so rich. Any help here would be greatly appreciated.
