[s-cars] Stumbling under acceleration.....probable boost leak? Or...

[Jim Fleischer]

Hey guys,

Thank you for all the responses to my stumbling issue......after a long holiday week and a quick 1500 mile round trip t Eastern Kansas (not in the S) I'm finally able to tart tracking down the issue.  Here's my plan of attack.....

1.  Will build a leak tester and check for leaks in the intake hoses.....

2.  If no leaks found, will check spark plugs and replace with NGK's as suggested by Dave Dawson

3.  If that doesn't do it, then will go the coil pack route.  One question, though.....if I am only experiencing issues at higher boost, but not during normal idle, how can I tell when there is a "miss" at idle when swapping out the coils?

4.  If that fails, well.....I guess I'll post again and see what you all have to say before I, "gulp" take it to someone.....

Thanks all....I'll let you know what I find in the days to come.....

Best regards,

Jim Fleischer
