Probably. But the excessive leak down would also explain the low compression. And although low, its not critically low.

I will admit I don't normally have to rely on computers to solve my problems for me. For the cars I do work on its I have much better OBD software, and even at that its a rare occasion that I'm so stumped I actually dig very deep to solve a problem.

Yes I did. First thing.

I have read where other people who have had the same problem and ended up with the same solution(s). From my understanding what happens the PCM sees the discrepancy in the 02 sensors and adjusts the fuel map, and that causes the misfire. Like I said: the new 02 sensor reads about the same...

I said I swapped out the parts (more than once I might add).

I got a Bosch direct fit from AZ.

Did some more testing today. Started looking closer at the values on the scanner. #2 02 sensor on left side was reading abnormally low. Turns out the PCM sees this and adjusts the fuel map. I think this is what was throwing the code. I suspect the problem is the CAT but we changed the 02...

Just tested the leakdown. #5 is leaking 10%, and it seems to be getting by the rings. #3 is only leaking 3% which is normal. I wouldn't think 10% wouldn't be that big a deal, but maybe it is on this motor. I also checked the rockers and springs and can't find any other problem.

Will the pain never end? Just replaced right side head because of a dropped valve seat. Then MAP sensor went out and replaced that (twice). Then the AC hose. Driving back to deliver the car to the owner and the CEL light comes on. P0305. Swapped out out injectors, coil pack, and plugs (which...

For further clarification: These guides have a plastic ramp on them that slides into the metal frame and a lock tab that holds it in place. In my case it was only the lock tab that broke off allowing the plastic part to fall off the metal part. But, there is a secondary system that will keep the...

OK, problem solved. Turns out the new MAP sensor we got was defective. WHen I checked the MAP reading from the scanner it was reading 37.8 Barometric pressure. On earth it should only be around 29. I also put a vacuum to the sensor with no change. The new sensor read 29.8 static and changed to...

Not my idea. THe owner said he didn't want to have the other side replaced as well. I think he's planning on selling it in the next year. The other guides will probably be OK as long as they stay in position.

So here is the deal now: I got the car back together. Started it and it was throwing a code indicating bad MAP. Yep, MAP broken. Replaced MAP now its showing code 1297 which basically means the MAP and the TPS are not on the same page. Vacuum leak? None that I can detect. I did read where...

As it turns out you can order the chain guides from AZ or pep boys. That takes about a week and there is some confusion on their web site as to which part is which part. Turns out the local NAPA warehouse had them in stock.

OK, I'm back at this. Got the head on, went to put the chain guides on and they basically fell apart in my had. Dealer only sells them in a kit for $450. Any ideas?
