Hi, I have an 04 G with manual trans. It has 87000 and goes through the typical 1 quart to 1000 miles. Today I checked it and It was low so I put a quart in. It started fine then after about 10 sec it started to stuble at idol and if It came down from anything above 2.5k it will stumble to death, Literally. I heard a small leak from the PCV are s I check and retightened, Checked the MAF and all vac lines. everything is fine. It through a code around the 5th time I started it from the stumble to death. After checking all of the before mentioned items, I reset the ecu incase it was a code causing the stumble. Still does it. It appears to run fine off idle, power wise, but sounds like there is a cylinder miss up to 2.5k. Ran fine before the oil went in as well. Thank you
