HELP!!! Srt-4 Bogging out and Throwing CEL - SRT Forums

Honduh · 10-30-2009, 12:11 PM

My buddy's srt 4 is bogging out real bad and almost seems like its misssing out. It will only build like 4 psi of boost. If it goes above that it starts cutting out. Also it will throw a cel and it blinks. Im new to this so help me out please!

mine was doing the same thing, only it was around 10psi. i bought new plugs and wires and set the gap at 30 and all fixed.
hope this helps

X2 on the plugs and wires. NGK 4306

Unless you're running some crazy high boost pressures, a gap of .035 to .038 should be fine. At stock psi a gap of .040 to .045 would do.

yup. NGK's and Granatelli wires

didnt happen to pull the codes from the vehicle did you? maybe that would be a good place to start instead of throwing parts at it?

Do you have a wideband?

If so what are your AFR's?

Running rich would tell us it's a spark problem.

Lean would most likely be the injector took a shit.
