Question Got error codes P2231 and P2234 and terrible idling

I got these two codes and P0171 and P0174 (bank 1 and 2 lean). P2231 and 2234 are the bank 1 and 2 O2 sensor heater circuit shorted.

What's happening is my car idles terrible. Basically, I had the car down for a couple of days. I replaced my alternator, rear diff seal, and some other routine maintenance. It would surge at idle but still ran fine. Figured I didn't tighten a clamp down.

So I went to the track and the idling got worse after each session. Either it self revs (worse than surging) or idles really rough and sometimes stalls. Once I get on the throttle, its fine. Still makes power. I noticed during the last weekend at the track that my AFR gauge would go to 21.8 at full throttle. As I applied throttle it dipped down to the 11s and the pegged at 21.8...I might have to recalibrate my LC1...not sure.

Will the O2 sensors be the likely culprit? Or is there anything else that could cause both heater circuits to malfuction?

I just got P0015 after the other 4 which I would assume is thrown because of the other 4 codes.

Now that I think about it...I degreased my engine bay and I might have gotten a little froggy with the water hose. Especially around the valve cover where I had some old greasy crud. So I may have soaked the O2 sensors which are a little lower with my AA headers.

At least my engine bay is clean!

Just replaced my O2 sensors. I'll run it for a bit tomorrow to see if things get better.

Checked all of that. No matter. I gave up and the car is at the shop. I think I may be getting boost at idle...bad bypass valve???

Hopefully you have a good shop down there capable of dealing with a modified car. Hope you get this resolved quickly!

They found a large vacuum leak. Apparently the seal/gasket between the laminova core and compressor is shot. So hopefully AA has the gaskets and got them in the mail yesterday.

At least you know what you're dealing with now! Are you talking about where the compressor bolts to the intake manifold? I don't think ESS even uses a gasket there, I think they just use some RTV gasket maker to seal it up so that's always an option if a gasket isn't available.

Found out that AA does not use a metal gasket but RTV gasket. The shop is saying the gap is quite large and they think the aftercooler body is warped. I talked to AA and they said that might happen if I cook the engine and the heat is conducted into the manifold and compressor assembly.

So I have to see it tomorrow. I'll probably end up trying to reseal it myself...need to learn how to take apart this kit anyways.

This wouldn't surprise me that some RTV failed. I'm thinking that my summer track days in 105+ degree temps contributed to this on top of the kit being 50k+ miles/4+ years old. To the credit of this kit, there were a LOT of cars going into limp mode and my FI'd 330 ran all weekend without a hiccup. I guess something had to give.

Hopefully the manifold isn't warped. I can't imagine ambient temps being nearly as critical as your oil and coolant temps so if you didn't overheat the engine and warp the head, etc I'd be really surprised if the intake manifold warped (even considering how the compressor is cantilevered off the manifold). Be sure to post up some pics of whatever you find.

Sure will. I will try to take it apart this weekend. If not, it will have to wait until next weekend.

So I picked up my 330 today...I was VERY anxious. So I talk to one of the techs who show me where the leak was coming from. It was between the aftercooler (not on ESS kits) and the compressor body. There was a significant gap that you could slide a razor blade through. Then the tech says, maybe those bolts are loose. Turns out he could turn one of the two bolts which bolt the aftercooler to the manifold by hand. The tech tightens them up and I drive off. It still idles crappy but it doesn't stall and there's not part throttle hesitation! It is WAY better.

So the good news is that it seems like a relatively minor and cheap fix. Bad news is I still have the remove the compressor/aftercooler/intake assembly and reseal everything and THEN hope that my problems are solved. Which I am confident it will fix my vacuum leak because I've went over everything else 10x already.

Glad to hear nothing is warped/deformed! Once you get it sealed back up, clearing the adaptations should help it run smooth again more quickly.

Yeah, I plan to get a smoke test as well. I have to call Active on Monday about some injector spacers, gasket, and a new supercharger snout bracket.

If you think about it...the compressor was basically flapping around. So I posted 1:57 and MSR Houston CCW and 1:30 MSR Cresson 1.7CW with my supercharger compressor half hanging off...THAT'S AMAZING! I'm still amazed. 4 days at the track with the car like this and I didn't baby it. I think about the few issues I've had and they are all self-inflicted except for 2 (door seals and ignition coils). I love my car more and more!

OK, got the compressor/manifold assembly off in about 1 hour. It was suprisingly easy. Now, only if the post office was just as fast at delivering my gaskets, I'd be all set!

I checked the manifold/compressor bolts on the bottom...they were loose as well. So I'll seal it back up, torque and loctite the fasteners tonight. Wait for USPS to deliver the intake gaskets and then reinstall. Clear the adaptations and do a smoke test to make sure.

Got everything back on...now the beotch won't turn over. It cranked, turned over, ran rough for about 15 seconds and then died. Won't turn over again. So I'm charging the battery up...will deal with it in the morning.

With patience, somoe battery charging and lots of cranking...she turned over and is running very well so far. Mostly smooth at idle. Still going to get the adaptations cleared and a smoke test. Hopefully on Monday.
