I have a 1995 Chevy K3500 with 454 cid engine that just won't run right. I have replaced Fuel Pump and filter, TBIs, Fuel pressure regulator, MAP, MAF, TP. O2, Knock,and heat sensors...I have replaced the EGR valve, timing chain and gear, distributor, wires and plugs, computer...even knocked out...
Ok...a little about me. I am a high school teacher and used to work as a mechanic...old school...really old school...never worked on computer ran anything. When timing was an issue I didn't have to check 500 things to get the timing right. This truck is a nightmare for me...for others it might...
