My car is a '99 3.2 TL, 163K miles
On the drive to work yesterday, the car starting shaking badly when acceleration, idling roughly (thought it was going to stall), and the CEL & TCS came on, with the CEL flashing. I took it to the local parts store, and the codes came back as cylinder misfires. I tracked the problem to one of the ignition coils, replaced it, and the car went back to normal (I thought). I drove it a bit last night and it seemed normal, and went to bed proud of myself (not much DIY experience with cars here).
This morning, all seemed fine, until, pulling into a drive through, the car starting idling roughly. It still accelerated fine, but 5 minutes later the CEL and TCS light came back on. The car performs fine accelerating now, just idles rough. I haven't had time to get the codes read yet, but I suspect they're the same.
Any tips as to what I should be looking at here? It'd be a big coincidence for another coil to fail the next day, and the symptoms are different. I didn't change the plugs out yesterday, should I? It did get driven around with the misfires for 15ish miles yesterday; could that maybe clog up the EGR and set off some new codes? I'll update with new codes this afternoon when I can get them, but any advice or heads up from the forum would be greatly appreciated! It's been of immense help so far!
