MY 1997 Z28 CAMARO STILL HAS A MISS AFTER I INSTALL ALL THESE NEW PARTS. I HAD A CODE P1441, AND A P0300 BUT THEM CODES WENT AWAY A COULPE OF DAYS AGO. BUT MY CAR HAS A SMALL MISS WHEN I COME TO A COMPLETE STOP AT A LIGHT. I CHECKED ALL MY WIRES AND THE PLUGS LOOK GOOD. CAN SOMEONE HELP ME OUT WITH SOME NEW IDEAS.

I don't know what those codes are, but I had similar prob with my LT1. Scan at GM said misfire- engine tune... I found my EGR valve was carboned up/ sticking. My car was automatic- under converter lock up (4th gear, cruise/light throttle) I felt it most. A simple cleaning of the valve was all that was required! Hope this helps. BTW you can reach around the motor and squeeze the diaphragm up- if it moves up smoothly and doesnt stick anywhere in its travel it is OK!

first of all thanks for the respond, i did check all the wires and plugs i also changed out the evac cantnser and the evac solied. this all started when i got a code of p0300. i replaced opti spark , plugs,wires, fuel filter. i found a burn wire off my o2 sensor on the passenger side on the extenstion side so i just put then together and taped them up. so i don't know why the car is missing when i put the car in drive , it just starts to miss out of no where. what can i do to fix this problem ?

You need to completely replace any burnt wires. Years ago I had my tranny out and when the tranny guy put it back in he left my drivers side 02 sensor wires leaning against my LT's. It did all the symptoms you are having....we simply spliced in all new wires for all 4 of them.

i finely found what the problem was on the missfire . i change out one of the fuel injector on cycinder #1 . what happen is that i ran my fuel very low. and thinking that i picked up some trash from my gas tank. i installed a new injector and put new plugs and the missing went away. dam i'm sure glad. i also put a new opti spark , new fuel filter.
thanks for yall 's input ....... I 'M SURE GLAD THAT LT1TECH. IS AROUND.
