Has an engine miss

Is the service engine light on? If so, get the codes pulled and post the code numbers here. Otherwise, we are just guessing and throwing parts, time, and money at it.

Aside from that, there could be a lot of things going on. A bad distributor can cause a miss. A weak coil could be it. A bad spider injector could cause it. Lack of fuel pressure could cause it. A bad crankshaft position sensor could do it. If you used the wrong plugs/wires that could be it too. If you crossed two plug wires when reattaching them, that would definitely cause it.

As a matter of fact, before you do anything, recheck your plug wire routing. I am attaching a diagram below.

Let us know and we'll go from there.

Yeah I do not like misfires. Such a pain to diagnose sometimes. Do let us know what the code numbers are. Hopefully they will shed some light on what is going on here.
