[s-cars] Cleaned cats, stumble and cut-out

[Jim Fleischer]

Thanks all who have helped me out with their suggestions......here's a response that hopefully addresses all points.....

As far as emissions is concerned, I have Montana permanent plates, and don't require emissions testing.  That said, my environmental conscience will dictate getting new cats eventually.

I've checked all boost hoses, cleaned the MAF and other assorted sensors as blinked codes have dictated. Currently throwing no codes, but still stumbling/cutting out.

I've been pulling the ECU fuses to clear the codes each time I mess with stuff.

I have yet to check into the ignition wires, etc. Hopefully will get to that this week (maybe today).  At 140K miles and original coils, odds are that might be my issue.  Does any of the diagnostic software address the ignition system?

Is there any way, besides pulling the injectors, to test the coils?  My problem seems to be only on full boost, so I don't think the injector test is going to help me out. Thoughts?

Thanks again all.....I truly appreciate the thoughtful suggestions that have me boosting at the moment.

Best regards,

Jim Fleischer
