Cat converter?
okay, so tried to replace the crankshaft sensor but finally after getting the crankshaft bolt out, couldnt remove the harmonic balancer! Apparantly the puller on this is different than any one that murrays autozone napa or carquest carries so i gave up and decided to direct my attentions elsewhere. I had removed one of the spark plug wires a couple days ago to get more room and had it snap off in my hand. I knew they were old but these were OLD. so I replaced all of them after struggling to get them off along with all new plugs. Now I put everything back together and it started smoking from the exhaust manifolds. More in the back than in the front. It sounds like its running strong and then its getting backed up! maybe i had a duel problem, the ignition module bieng bad, along with bad wires and plugs, were creating improper ignition, and thus improper exaust? This maybe caused my cat converter to back up faster. The exaust itself is pretty f-ing loud and it looks new from behind the cat. does any of this make sense?!? Im going NUTS!!!
