thanks for the suggestions
yesterday, i cleaned maf, egr switchover valve, and idle rasonance valve. no difference. idle @ 1500, i can live with it for now, but cold start problem is my concern. i have apptt scheduled with independant mechanic who will charge me $35 to check fuel pump, vac lines, and diagnostics. and $85 to replace fuel pump, if needed. i will keep updating, so that other forum members can benefit from my experiences.
