EF power flat spot, what the...?
I have found a very odd problem, under hard acceleration, in power mode and economy mode I will find that the car will haul along until about 3500rpm, then just flatten out in power until bout 5000rpm when it gets a little jolt before changing to the next gear. I just want to know what is happening? Is it to do with the fact that it has a standard exhaust and intake so it isnt getting enough air into the engine?? your thoughts please.
Just a side note, this car is going to get a T-series intake snorkel, K&N panel filter, EL intake pipe from manafold to EF airbox, Pacemaker Extractors, 2.5 single muffler mandrel bent exhaust in the next week or so.
So would this help the situation??
The car is a 1996 EFII Fairmont Ghia, featuring 4spd auto, XR6 164kW motor and has 3.45LSD
Cheers for your help in advance,
