Jeep Grand Cherokee died suddenly at 50 mph
Today I was driving along at 50mph in my 2002 Jeep Grand Cherokee Laredo 4.0L when suddenly it felt like I lost half the power. A few seconds later the engine died. I coasted to a stop and was able to restart the engine numerous times. It would idle fine but as soon as you gassed it the engine would start misfiring again, sputter and stall. It did this a few times and now it won't even start at all.
I did the key trick and received 5 error diagnostic codes:
P0340 Camshaft position sensor circuit malfunction
P0351 Ignition coil A pri/secondary malfunction
P0352 Ignition coil B " " "
P0353 Ignition coil C " " "
P0455 Evaporative Emmission Control System Tank Detected (gross leak)
I believe the the P0455 was present before this cut off. I think that code is due to an aftermarket gas cap.
The other four codes are what have me concerned. Can anyone offer any ideas as to what would make those codes all come on at once? Seems odd that all coil packs would fail simultaneously.
Where should I begin? At first I suspected a fuel filter, but now after seeing the codes I don't think that is it.
