Just an update,

I switched the OVP from the used ebay OEM one that looked new to the new Chinese one with no difference. Each time I've done this it runs great cold and starts the random dropping of cylinders when it warms up to normal temp. At that point the more you drive it, the worse it gets to the point it doesn't want to move off idle. Once off idle, it clears up and runs fine.

Also removed and cleaned the MAF with CRC MAF cleaner. That actually seamed to improve off idle acceleration and power but did nothing for the initial problem.

And it seams to be getting terrible gas milage.

PeachParts has a rebuilt Throttle Housing,Part #: 000-141-57-25-81-INT
by Beckman Technologys for $920. Does anybody have any experience with them? I don't mind spending the money if it cures the problem

Anymore thoughts, please

Thanks
