we got misfire just when cold ,if acelerator is press ,once engine warm runs fine
this happened after engine repair
The codes indicate miss fire on #1+3, these use a common coil (waste spark system). Check the wire harness for poor condition.. Philip

coils are new ,the problem its only with engine cold ,if you start engine cold and press acelerator the engine idle goes crazy and stall ,then crank without compresion ,you wait few minutes and start normal let the engine warm up and runs fine .

Please read and understand my post...BOLD

I did not refer to the coil or the H/T plug wires....

You probably hove a low voltage situation which makes firing cold plugs and fuel difficult....
Are your plugs gaped to .044"?
Have you verified a good engine ground?? ... Philip
