Tried replacing FP regulator this evening to cure my overly rich mixture. Car ran about the same as it has very other time I have cleared the code. I don't feel very confident that my problems are cured. Looks like I will be pulling the intake for a good cleaning and a cold start injector check next.
A Recap of my blues saga:
Light comes on codes tell me rich or lean at idle, then at cruise...
Check 02 sensor good voltage
Check CTS good resistance
Clean AMM and find ripped air filter, replace filter clear codes light returns in a day
Gumout Throttle valve cause it has some oily grunge in it, so does duct from AMM...give that another spray... clear codes...same
Change FPR clear codes, Next verse tomorrow
