Hi! I have a stock 95 cobra that I've had since 1998. It's always seemed to have a HP issue, but no-one could ever really pin it down and I didn't have the money to persue it too much so as long as it ran I ok I went with it. It suddenly got to the point where it wouldn't go above 30mph and I took it in to the shop where they said it was a bad MAF and they swapped it out. Suddenly the car was screaming fast(well for a stock 240hp) and I was happy as #$%Q. After about two weeks I noticed a decrease in acceleration/hp and it just got worse to where it was the same as before where the car seemed to run just fine but it wasn't that fast. I brought it back, they swapped MAF's and once again it was fast a %#$^ again. A few weeks later, same issue. I lived with it, but when it started to really have issues again a few months ago I swapped it out for a PRO-M MAF/filter combo and it runs really well........ except after about 5 minutes at idle. Then it starts to surge with the RPM's dropping really low almost to die and then recovering for half a second to repeat and the voltage goes low as well. I've unplugged the MAF and it runs better(steady, no rough idle or surge) without it but of course the CEL is on. I replaced the battery/alternator/coil/fuel filter/cap/rotor and wires with no effect. I am starting to think computer but I hoping someone has had the same issues and can point me in the right direction because everyone I talk to doesn't know what to do. Thoughts? Appreciate any help!
