U best hurry. There in North Texas, the Artic Winter could start at any time, then again your just as likely to be running around in cut-off in the mid 70s in Jan. You already know that the barbed wire fence across the kansas border makes a lousy wind break.
Now at part trottle, what is your nominal boost, & RPM that your noticing the flutter?
Is it constant at a certain rpm or noticable as you pass through a certain rpm?
Might you be feeling ignition: as in that majic pressure/fuel mix where you can find a week coil? I thought you had an extra parts.
Any chance you have set of coils?
Didnt i read you are running 1 step colder plugs, yes?
And you know,you have good 93 fuel?
Does OKC check for cats on inspection? If not, and your not running cats, head over to Wiley Post, or guthrie-edmond regional and score 5-10gal of 100ll .....for your lawn mower....errr garden tractor.....weed-waxker...whatever.
Mind you, O2 sensors will not like this for long but they will work...for a while..
you can deal with and test non working sensor. Pita to crawl under but still workable.
Now you might some help from,a shop on the broadway extension in Edmond...Think it is called Mike's
Check that, it is called Metric Motors 2608 South Broadway | Edmond, OK 73013
