Car misfires
Hi guys,
MY LT1 (92) has been misfiring for quite a long time now (about 2 years).
At the begining I had a code 43 together with this problem. I changed the fuel filter, the spark plugs, checked the wiring...the problem remained...
Then I had a code 16...So I decided to change the knock sensors. That solved the codes problem (I have no code stored now).
But the car still misfires, and this happens randomly (speed and RPM varies from one occurence to another) and this doesn't happen every time, one day the car may run fine and the day after it can misfire (though it occurs at a random speed it is in the cruising speed range)
Help me solve the problem guys
Thanks

Sounds just like my car used to be. Any hard starting trouble? Any fouled plugs? Mine ended up needing injectors. Runs strong once again.
