problem
It started off I noticed my times at the track were falling off, then I noticed a little rougher idle and now my car wont take nitrous, when I try to spray it it falls on its face. No detnation and it doesnt smoke.
I checked my solenoids and both are working fine
Its not throwing any codes
I called the dealership about a diagonstics and ask them if I had bad coil packs or injectors if they could spot them out and they said there is nothing they can do to my car because it has a aftermarket tune in the computer and aftermarket parts on the car.
nothing has been changed on the car from the time it was running fine till now
It has new plugs,fuel pump and filter
