Help!!! Misfire
I have a 98 camaro , I was driving it home car was running fine doing about 60. Got off on to a main road and slowed down to about 35 and the car started missing and pulled the ses light then it started flashing. I got it home and run the codes po 307 #7 misfire, po351 coil 1 malfunction, and a po353 #3 coil malfunction . Changed all plugs and put in new ngk tr55, and two new coils, now still got the #7 misfire. Any suggestions?
