code H 64
Been having O2 sensor right side cat front (lean) H 64 code, interminted service engine light and slight rough idle. found frayed wires on sensor wires fixed them no more service engine soon light, still slight rough idle. today while doing about 40MPH jumped on it for about 5 seconds got off it and now runs with a little hesatation and miss while driving never did that before until I got on it a little. Still just reading the H 64 code, do you think this O2 sensor related or did I mess up something else. This is a 95 with 70,000 miles previous owner did tune up as I can see not stock plugs and wires. The car never had any hessitation with power before this. Thanks, Joe

joe If it were me I would try to locate what cyl the miss is coming from. you can disconnect the injectors one by one till you get to the one that makes no difference when you disconnect it. from there it is simple it has to be plug, wire, something effecting fuel (ie injector wiring), or something gone haywire in the cyl.

don't jump that far lots of testing to do first. anything from wiped cam, burnt valve, on and on. Like I said don't jump to the worst case. take it one at a time. if you can feel the miss you can locate the cyl where it is coming from. and find the problem.

Took the Vette to church today not as bad ,upon initial acceleration slight intermittent surging,3rd and forth gear (auto) hardly noticeable at all, full throttle no problems. I am going to put in new fuel filter and Bosh 3's this week. Still getting slight carbon build up on bottom of Magnaflow tips,so maybe I should change the 02 sensor for the H 64 code I can't seem to clear using the paper clip method.
