Hi, My question is, on my 88, pulled it out of hibernation , got a code 34, checked connections at maf/map, still get code, what puzzles me is that after it reaches operating temp. the SES lite is gone and doesn't come back until next cold start???? Any ideas???? I love this site, it takes the uble out trouble shooting...............Thanks

code 34, checked connections at maf/map, still get code,
Work through the diagnostics

MAF code 34

"A Code 34 could be set for several reasons as well.
A bad ground, an opening in the ducting between the MAF and the throttle body,incorrect minimum idle-air setting of the throttle body,
or a worn throttle body can all cause a Code 34.
Typically, a worn throttle body or a bad ground will set a Code 34 intermittently
