Recently I've been experiencing a sputter/loss of power while driving I also get the occasional cut off (stall) while stopped. After speaking with one of my coworkers he suggested I put some Seafoam in the tank which I did but continued to have the same problem. I then took it into a local mechanic who swapped out of my fuel filter. Long story short I'm still having the same problem. Its been maybe a year or so since I changed the wires and plugs. Outside of that is there anything else I should look at?

Need to check your fuel pressure.

Okay. I'm not too familiar with doing that. Guess I'll just drop it by the shop at some point.

Is the check engine light on? Otherwise the Delco Coil swap would be a good upgrade, and would rule out coils/ICM.

Update. I swapped the plugs but not the ICM seems to run fine. Will replace the ICM once the part comes in the auto store.

What about a plugged cat and/or a faulty Crank Position Sensor?
