THIS IS EXTREAMLY LONG REPLY BUT REALLY DESPRITE FOR SOMEONE NICE TO HELP ME Thats exactly how i discribed it, no downshift. and i have already bought a dh pcm second hand but updated, but have not installed it yet, i had mentioned before i bough some parts from PFYC, a 3.4 pully and a 3.2 pully just to have maybe change in the future, im going with the 3.4 for now, gator back v-belt's, speedbuilt fenderwell intake, which is already installed, and a 180 degree thermostate. and im about to purchase the straight pipe to replace the u-bend, and some coolant, give er a nice coolant flush, i have already replaced fuel filter, and pump, ignition coil, two plug wires, and air intake. BUT!, i heard that if you add an air intake, new pcm, thermostate, and what ever else, that it could make my problem even worst, but then again what is the problem, could be 10 different things, i stayed up till 3am this morning doing research trying to figure out what it could be, but the symptoms i have listed a few possibilities, here they are,
TOURQE CONVERTER
SPARK PLUGS (ive already changed)
FUEL INJECTION SYSTEM ADJUSTMENT
FUEL FILTER (ive already changed)
FAULTY SPARK PLUG WIRES
INTAKE MANIFOLD AIR LEAK
VACUMM LEAK
DEFECTIVE/NOT FUNCTIONING RIGHT ECM
FAULTY COILS (could be did change one when i first bought it last fall, coil tower was rusted)
BRAKES BINDING (everytime i start the car and put it in gear and start moving there is always a quick rubbing sound in the front like when anti-locks activated the sound it makes it the same is this normal?)
TRANNY FLUID LEVEL INCORRECT (well in the tank its about an inch over the top line and stays there, so i think! and the dip stick is fine, smells fine, looks fine i replaced the tranny twice in my 97 gtp so i know what to look for and listen for so i dont think its my tranny, this is why i need to see if it is the TC cuz if it is then it will frig my tranny right?)
LOW OR UNEVEN CYLINDER COMPRESSION PRESSURE
CARBON IN COMBUSTION CHAMBERS
DAMAGED IGNITION COMPONENTS
THROTTLE VALVE (is what i thought it was from the start)
SHIFT LINKAGE
TRANSAKLE MOUNT
EXAUST LEAK/NOT SEALED
