I just made a run from northern CA to southern Oregon. All was good on the way up but on the way back I noticed some surging, especially when at light throttle on flat road or off the throttle going down hill (coasting but still running 2000 rpm) . I switched tunes from my MoparMan mileage tune to the tow tune and no difference. I also hit the overdrive button and no difference. Fuel pressure was always 15lbs or more. By the time I got home I had a check engine light and it was 0236, Map sensor. I have cleared the codes numerous times and I might get away with driving a hundred miles or so with no code but the surging continues. A day or so later, the code comes back.
I don't have boost shown in the Quad display since I have a separate boost gauge directly off of the intake elbow. I can't remember, does the Quad boost value come from a fitting I don't have installed in the intake/head or off the computer data?
Any help before I start replacing parts!
I read somewhere that the Quad has some known boost value issues and some guys run a separate boost fooler connected to the stock wiring harness and disconnect the Quad completely from the map sensor circuit, is this a way to start troubleshooting?
Thanks!
