hello guys I'm real happy to be a new member. I have a 03 neon r/t 35,000 k. while driving it suddenly started missing on the number 1 and 2 cylinders. the system flashed no codes, it has fire from the coils, good compression. I replaced the plugs and it made no difference, got the injectors clean and switch them from 3and 4,no difference. I am really lost can someone please help. thank you

 

Welcome to the site. I will move this thread to the second generation Neon section,

how do you know it cyl 1 and 2 if there is no code. the spark is a wasted spark system 1&4 fire together 2&3 one of those two it could be the coil or cam sensor. but if you are sure it ain't spark or fuel. then maybe it is timing related maybe it jumped a tooth but

 

also check the wires but i had more coils go bad then wires so check that, and too slow has a point. only way to know which cylinders it is if there are no codes?
