01 Blazer Lt SES lgt, Misfires
2001 Blazer lt 4.3 Service engine light appreared on 100 mile trip, at one point it flashed then stayed on car hestitated internitemtly. Parked car overnight, needed jump in morning. Car started w/jump no SES lgt car ran some what correct. Spoke to mechanic friend said it could be wires or pluggs. Suggested to open it up on highway, did that and the SES light came back on and car misfires again. Didn't change wire and pluggs yet! Moneys tight, just wanna make sure before I attempt a cure. Any suggestions.

Plugs, wires, cap, and rotor are typical tune up pieces. If you do not know the origin of the parts that are on your truck now, it would be a good idea to replace them as preventative maintenance.
You can check the wires by misting them down with water in the dark with the engine running. You are looking for sparks jumping from the wires to any close by metal.

Thanks man, thats a great and simple method for a light show @ no cost. I'm the second owner and bought it w/40k on it. So I appreciate any help given. Do you know a decent set of wires are for the car and what are the lengths for each plugg. A freind had said unless you buy specific you can get varying lengths. Again thanks you guys are great.
Thx,
