Stuck with code P2096... I have just cleaned the MAF ( I've been told the IAT is built in to the MAF)? I pulled the air box to see if the filter is dirty ( Somewhat- but not horrible) However... where the air tunnel starts, I feel like it's NOT been sealed properly, the top of the "Tunnel",
where the air box is inserted, looks to have been bent and probably leaking air before the filter. Yeah I'm a newb, so If anyone can point me in the right direction, it would be greatly appreciated Thanks

Do you mean the accordion tube that goes from the air box to the intake? If so, just need a clamp to make that seal.

BGunner

no sir.... there's an OVAL opening on the front where it picks up fresh air... it has a foam gasket. that gasket is in sad shape : )

CaymanRotary

ohhhh ok I know what you are talking about now. Doubtful that's causing your problem.

Yeah don't worry about that gasket or anything before the MAF sensor. Anything after the MAF sensor is important though.

Can you get your fuel trims at idle ? Sounds like they're maxed out due to a vacuum leak

DTC P2096

Vacuum leak is my bet, as well.

Start the engine, let it come up to temperature. Check your MAF rate and LTFT at warm idle. An LTFT of +/- 8% is no big deal. Your MAF rate at warm idle should be 4.5 - 5.5 g/s.
If your MAF rate is less than 4.5 g/s, you probably have a vacuum leak (and your LTFT should be pretty high).

Ok I'll start looking for Vac Leak... Bank 1 o2 is too lean. I'm chasing this down if it kills me. Thanks

BGunner

I'm going out to check for vac leaks- Thanks Loki

BGunner

Ok.. so the MAF is 3 .1... LTFT shows 7.8. I can't HEAR a Vac leak, but I know you can't always find it that way.. it'd be WAY too easy LOL... Also have code P0137 now

Just buy a cheap cigar and disconnect a vacuum line and puff the smoke in. Works for me to find vacuum leaks.

3.1 of what unit? Seems way too low for g/sec.
7.8 LTFT isn't terrible. What about STFT?

P0137 sounds like damage to the rear O2 sensor or its wiring. Maybe a blocked catalytic converter (which is bad news bears)

wellll, after a stiff drink, I thinking about it... My girl Vapes, Soooooo (ya see where this is going?) Cigar No.. Vape... yupperz

I replaced the downstream O2 last year after the clutch was replaced. If it's the Cat, what do you suggest? Any good aftermarkets that ain't $1,000,000?
I replaced the O2, Cat,and put a 12" glasspack on 96 cherokee, baby runs great, and pretty low muffle but lots of flow. Melissa wants to give the RX8 a lower purr,
but all the after market stuff is expensive and I don't know how to get the sound she's looking for. I'm a Chevy Guy, with a minor in Jeeps.. lol

One step at a time. Take the cat down and confirm the problem before you spend money on a new cat. Don't go cheap if you do have to get one, it won't last.

CaymanRotary

I'm old fashioned I guess. Maybe I'm getting old...

CaymanRotary

Buy a cheap cat for emissions, and as soon as it passes toss a midpipe on. Best solution there is for this car. Also get an air pump block off kit so you can keep it off your car and can reinstall for emissions.

BGunner

That's pretty sweet- I just made an appt. to go see my muffler guy tomorrow.. Thanks guys!

BGunner

sorry Loki, just backed up and saw your question. Maf was 3.1. like you said 3.1 MAF is low. I'll check the stft

Loki

But 3.1 what? Is that g/sec? If so, that's mighty low, you have a huge vacuum leak somewhere.

NotAPreppie

What Loki said.

You have a vacuum leak. Time to smoke out the intake.
