DO THESE QUESTIONS EVER GET RESOLVED

Don't know? What kind of problem? Some questions I try to answer. Some questions, I can't answer. I can only help with testing, some issues. I don't search too much for unanswered questions. I just come here to kill the time of day. Just speaking for myself, I don't get paid for answering questions. I try to pick the easy questions. lol

Since this a public forum, the questions get answered when someone has time or knowledge.

People that ask questions here assume we are mind readers and know what the issue is without telling what the actual problem is. You know the thing man, the thing!

May be you want to ask google and find the owner's manual for your car problem; or better find that in youtube and see if there are people already told you the answer there

Wow! Thank you everyone who replied I was having trouble with my 91 chevy blazer 5.7L idle and ignition and with what I'm kinda leaning towards is there's a '' induced electrical noise" according to my shop manual . The manual acknowledge this can be a problem but nowhere in it does it say how to fix it so I'm trying to insulate the computer harness and surrounding wires I'm sure someone out there has dealt with this. Thanks again

You may want to upgrade the plug wires. Get a top grade 8mm set.

Thank you for your reply, that is exactly what i'm doing now the best I could find and yes they are 8mm. Thanks
