My car now has about 66,000 miles on it. WHen reaching rpm's around 3000 and higher it tends to get sluggish and make a weird noise coming from the passenger side in the feet area. (I think). Could be the coils. I have read many of the threads and the problem seems similar but this does not happen all the time. Some times it runs its has off and some times not. When the ac or heat is on it seems to be worse. And it is throwing no lights. ANy suggestions would be great.
