- 2003 XLT
Hope someone has a fix for this.
I have a 2003 XLT with the 4.0 V6 2 wheel drive auto with 168,000 miles. I first notice a surge or a miss while driving at highway speeds with the cruise on. It wasn't only a month or so before the Check engine light came on.
Read the codes and it had a p0303 #3 engine misfire. So I change the coil pack and the #3 sparkplug. Didnt help. I read on this forum that it could be the O2 sensors so I replaced all four. That didn't help either. But I didn't feel I lost anything there since they were way past their routine maintenance replacement.
But now the check engine light is not only on but it flashes and the vehicle surges bad at around 45 mph, smoothes out above that. Read the codes again now it has p0303 and p0316. New one P)316 misfire the first 1,000 RPM's Talked with the guys at autozone and they thought it might be the Crank sensor weak or intermittent. Replaced that no help.
Replace so far
#3 plug, new coil pack, all 4 O2 sensors and the crank sensor. Nothing has helped it just seems to get worse.
Whats next injectors? cam sensor? MAF sensor?
Any help would be great.
Thanks
