Plug wires not correct? Confirm both engine side and rotor side. 2 don't sound right.

Did you pull the distributor? Sometimes it can be put in 180 degrees out or backward. Make sure it is correct. Sounds like a wiring mix up somewhere. follow the diagram to the plugs themselves to make sure. Could always be a bad wire or bad cap on the distributor. It is electrical in nature for sure.

I have a 1999 Chevy Blazer, 4x4, 4.3 vortec. We have changed the coil pack, fuel filter, distributor cap and button, the crank shaft sensor, cam sensor and plug wires as well as the ignition control module. We coming to a stop sign it will stall and sometimes when just sitting still. Sometimes it will start right back up and other times it takes several tries. I also have the oxygen sensor on order and it should be here tomorrow. Fuel pressure tested perfectly. No black smoke, no smell of rotten eggs or the cat glowing red. The only code that comes up is PO420. 4 Answers
