Engine stuttering when accelerating.
Hi all, I'm hoping you can help. I have a 2002 Mustang V6 (3.8L). She starts up with no problem but when shakes wildly when idling and under accelerations stutters and has very little power. She fels like she wants to stall but hasn't yet. Last week I went to Discount Auto and had the codes read which showed cylinder 1 misfiring and incorrect timing for under 1000 rpm. In the laqst week of minimal driviing I've already installed 6 new platinum 2 spark plugs, plug wires, fuel filter, air filter, and ignition coil. Yesterday I went back to discount auto and it still reads cylinder 1 misfire, bad timing under 1000 rpm, but now cylinder 3 is misfiring also...
At a loss for what to try next. Could it be clogged injectors, a bad fuel pump, or should I skip those and go to the ignition module? Recommendations?
