I apologize I was confused and we did not do a leak down test. Threw some oil in it and it went up 30 psi. I agree and I don't think this is The same issue. I ordered an Arrela and should be here soon and I'll post live data in a few. I'm sorry about that

I apologize, you're right, this is an unrelated problem. I ordered the Arella OBD2 wireless adapter and it should be here in a few days. I will post live data when it gets here later this week. Thanks again for helping me out.

Not sure anyone reads what I write sometimes??

From my post above:

"I usually suggest getting the OBDII interfaces from Amazon if you are located in the US/North America. Make sure you choose an interface that indicates that the order will be "Fulfilled by Amazon" otherwise you may be waiting for WEEKS for an interface to arrive from Asia. Ebay is another option, but pay attention where the interface will be shipped from, again weeks for an interface from Asia, so if you can wait and want to try to save some money, go for it, but if you need an interface soon, choose wisely."

Arrela is fulfilled by Amazon, which doesn't guarantee anything.

Not sure what you are talking about.

If you look CLOSELY at the description, the current Arrela ELM327 states "Ships from and sold by ToysNGamesEtc."

I buy a LOT from Amazon and everything I buy that states "Fulfilled by Amazon" is usually here in a few days without a problem. This typically means the product is somewhere in Amazon's warehouses and not being drop shipped from some country in Asia.

Put the cats on and o2 sensors. It solved the misfire codes runs pretty well. A few nights ago i changed the CCV as well as the Y boot that connects to the throttle body. Its still throwing too lean bank 1 and 2 and p1193 but the car runs beautifully. No more misfires and idles like a dream. As for the lean codes, im hoping its just a vacuum leak somewhere but the main problem is fixed. Thank you all for your help.

One sure fire way of checking whether your MAF is bad is very simple - does your cruise control work? The cruise will no longer function with a faulty MAF. You can turn the cruise on with the I/O button but as soon as you put your foot on the brake, if the MAF is bad, the cruise light will extinguish and cruise wont work. This is probably the simplest way to test the MAF and doesn't require a code reader.

Having said that - get yourself one!

Cruise test may be useful, however, if the MAF is hard failed, you will have other codes other than just Lean codes.

Assume you have an OBDII interface and App now?

There are a BUNCH of counterfeit Asian MAF's on the market and often a perfectly good OE MAF is removed and replaced with a crappy Asian Counterfeit MAF. Then I bang my head on the wall because the people I am trying to help keep telling me they have replaced the MAF so the MAF cannot be the problem! I tell them to put the original OE MAF back on the car, then we will talk.

But in the short term, I need to either see Logs, because this way we can see all the data and this saves about 20-30 questions, or you need to provide warm idle and steady highway cruise Fuel Trim values for review.

Also how did you confirm the O2 sensors are connected properly?
