I bet it is the ignition module, have it tested at oreillys or autozone, it is what the coils bolt to, common failure, or possibly a crank sensor

SOURCE: engine miss at idle. cylinder 1 and 3 has no fire

Try the ignition module.This is more than likely your problem.It is on the coil pack where the wires connect to.I have had a few of these go on me.This should take care of your problem.Hope this helps.Good luck.

SOURCE: i have engine oil under the ignition packs.

IF YOU GETTING OIL AROUND COIL PACK.MORE LIKELY YOUR PVC VALVE CLOGGED. ITS ALLOWING CRANKCASES PRESSURE BUILD UP CAUSING OIL TO BE PUSHED BACK UP IN THE PVC.OR COMPRESSION RINGS WORN TO A EXTENT THAT THE CRANKCASE IS OVER PRESSURIZED. FORCING OIL THROUGH THE PVC VALVE.YOU HAVE A PVC VALVE NEAR THE COIL AREA.THAT COULD BE WHERE OIL IS COMING FROM.

Firing order buick 3800 .if plug wires crossed up /how do i fix


I belive the coil pack on this is numbered 1-6. On the motor, front of car from passanger to driver side is 1-3-5 on rear near firewall from passanger to driver side is 2-4-6. Find coil pack and trace wires to each cylinder, if numbers match all is goo.
