I have a 2001 GT Mustang. Got into it this morning , first I noticed the RPMs starting dropping & going back up to where the car almost stalled out. Started smelling a burning smell shortly after but you can only smell it from inside the car & now the check engine light is on. No idea why my car is doing this!! Help!! .

hey i had a simlar prob not to long ago my self on my 01 gt, turned out i had a short in engine harnesss and was shorting out my coil on plug's , at one point one was smokeing pretty good, ended up getting whole new harness/used harness hasnt happened sence,theres a place in atlanta prestige mustang you can get another one from for about 140.00
, you want get a new one, the ford dealership told me they are no longer made because of low demand

step one would be check the vehicle for obvious signs of smoke or things leaking, next step would be scan the codes.. asking us what to do without being there with the car isnt going to help you at all

What he said in spades.

bet the code will be misfire code ,along with a short to ground circuit malfunction code

I am having and issue with my 98 gt. It hits the Rev limiter at 4000 rpm in neutral and while driving. It runs rough at idle and sputters and Jerks while driving. It also throws a p0340 code. I've changed the cam sensor and the alternator and it still throws the code. Anybody have any ideas?

make sure the cmp sensor connector and wiring are still intact, but sounds like you need to verify base engine timing. could have a timing/timing chain issue

check your tps also, it will cause some of those issues
