Hola
Trying to sort out why my 91 is acting up.
What happens is i'll be cruising along suddenly lose all power. Still have electrics. It's doesn't "bog" like when you suddenly lose spark, it's like i've taken my foot off the gas. It doesn't die, just goes down to idle and there is no power available. So far on each occasion i've been able to put it in neutral, leave partial throttle and it will suddenly run right as rain.
The first time it happened i did the natural thing for an Alfa Romeo guy and gave her a good ole italian tune up. I ran it full throttle up to redline through 1st 2nd and 3rd a few times and the problem went away for a few weeks.
Then it started again last week. It's never been very bad, lasting only a few seconds.
Only last night it happened twice on the way home from work and i actually spent a minute on the shoulder of the highway before i got power back.
The truck is pretty new to me. It has a check engine light. paperclip trick reveals o2 sensor. The nut of course is rusted to the stud and i can't get it off without wrecking it. Someone with more savvy than me is skeptical that it's an o2 sensor and is suspecting part of the smog system. I'm in Oregon and i can de-smog it if i want.
So not sure what to think. MAF? TPS? o2? Cap & rotor? In what order to i do start replacing parts?
