Lurching under part throttle

[PhastPhil]

Here is my enigma:

Just got the head back on my R/T. Was running great, and still does under WOT conditions. But now at part throttle the car lurches in unison with what I see as the up and down flow of fuel as indicated by my air/fuel meter. Then the check engine light comes on (havent checked the code just yet as it started this today). But like I said, WOT and the car runs great. Also, I turn the car off and start it again and the check engine light is off. Does anyone have any clue as to what the culprit is? Thanks in advance.

Sounds like one of your cams are off a tooth.

Thanks I will check that this afternoon. Anyone else have any suggestions?

[PhastPhil]

Well I checked my codes just now. Besides a 12 which I knew about I got a 27 and 43. I am going to start by checking all the wiring for the injectors and harness and also for the ignition coil to power module. Any suggestions still appreciated! Thanks.

I think my car started doing that when I removed my check valve from by BOV vac line. I wanted it to hold a bit more boost and when I started to let out of the throttle it would quickly stutter between boost and vacuum. At least I think thats what was happening... Good luck

I made sure all the electrical connections were sound. I also adjusted my fuel pressure slightly. Runs like a top at the moment. I will keep you updated. Does anyone know if the DC area turbo dodge meeting is going to be at Tysons Corner again this month? Thanks.

Any codes? Sounds like a bad map or baro read solenoid.

Yeah I got codes 27 and 43. I checked em both online. I did what I could to check all the associated connections, then fiddled with my fuel a little. Running great at the moment. I think the whole setup would be smoother if I had an SAFC.
