I bought a ZZP Stage 1 Supercharger Kit on black friday. Well I got the kit installed over the weekend and flashed my updated trifecta tune. Got in and she fired right up and seemed to run pretty smooth. CEL was on and the AFR was jumping around 11-15. Plugged my scan tool in and I had a P0107. Shut her down after about 10 minutes and finished tweaking/installing my front clip. Some time later I finally took her out on the road and drove for a bit. Gradually get into it some more just to see how she does. Finally went WOT and grabbed third... I had the biggest grin in the world. The boost gauge was standing right on the 10psi mark and the wideband was bouncing around 10-13. Took it back to the shop to check for leaks and shut her down (and she hit a couple times trying to run on).

Everything looked good so I got back in and hit the starter. It started right up but it was popping out the exhaust and running really rough. Hit the accelerator and after a slight hesitation it revved up and come back down to really rough idle and stalled. As it stalled it said Eng Pwr Reduced, Eng Disabled. So plugged my scan tool in and this time I had P0068, P0107, P1682 and B2AAA. I cleared the codes and unplugged the battery until I could figure something out. The P codes all seem to be pointing to the MAP sensor. But the install instructions never said anything about doing anything with MAP on the 2.2. The plug on the blower and the intake manifold are pressed in.

So doing some research online and now I'm really confused. Everyone seems to say that blower needs to be plugged and the bottom well, that's the debate. Some say that the L61 doesn't need it, others claim you should use an LSJ and others seem to say get the J-Body MAP or T-MAP. Probably should confirm it with ZZP, but I wonder if Vince tuned it for using the LSJ MAP sensor. Now I plugged the battery in and the car runs like a top. Didn't try to restart cause I figured it would do the same thing as it tried to run on after shut her off.

On a side note, I didn't use the Autolite plugs ZZP sent over and opted for NGK LTR6IX-11. Got all that? Good.

Well got my MAP sensor fixed, ZZP told me to hook it up per the install instructions for the 2.4. Now it seems to run a little worse than it did before but I didn't get the initial CEL. After I got back I let it idle for about 5 minutes and shut it off, but it tried to keep running a little bit longer than it did before. So I tried restarting it and it fired right up and threw a CEL. This time I had three new codes, P1682, P0121, and P0172; B2AAA came back for whatever reason. Ran about 3-5 seconds and then started idling rough and I hit the throttle to keep it running. Then seemed to idle fine for about 15 seconds then it just stalled. Then its rinse and repeat.

Gonna check the battery voltage while cranking and see what I get, but I don't think the battery is the issue. As for P0121, I'm going to check for an air leak in and around my air filter/maf sensor and double check the line coming off the fitting on the lower intake manifold to make sure its not leaking any. Then I'll give Vince a heads up and see what he says.

IonNinja

are you using the stock MAP sensor?

nathanroe72

Yep. Jason at ZZP said to use the stock (at least for now) and make sure Vince tunes it accordingly. Still not sure what the best route is especially for my model year.

2.2balt

Sub'd. Doing same thing with same year 2.2 lol

P codes 1682 and 121 are both related to throttle control. If you soldered 6-8 pin i would definitely look there. TAC doesnt seem to know wtf is going on.(keep in mind it is its own module on the network)

scagnetti76

172 is long term fuel trim code, which still leads me to believe its an incomiming air problem. Be it un metered air or TAC guessing where to put the throttle blade. Hope that helps.

scagnetti76

TAC and MAP are both load indicators to the ECM.

scagnetti76

So between the two, the ECM is getting mixed signals and its saying **** it,im going into limp mode. Just like listening to a woman. Hahaha.

Well now I'm getting a P0300 so I guess the logical thing to do is pull the plugs and check the gap and for fouling. I'm gonna say its spark blowout cause the way it comes and goes.

I got the ZZP Throttle Body Harness so guess I better pull it off and check the pins for continuity.

Well after all she is my girl so there I go. lol

Probably ought to rename this thread to nathanroe72's build now seeing how I got the original topic taken care of now (or so I think).
