getting so damn irritated with this car

mystk96 · September 13th, 2010, 09:19 AM

my 96 cobra has an issue that if you free rev it the first rev it will rev second rev it will bog down third rev it will stall. when driving the car say i go from 2nd to 3rd hell 1st to second at say 3000 rpm it will bog down for a second then pick back up.

i replaced the fuel pressure regulator, fuel pump, and fuel filter

the fuel pressure regulator is another new one.

i havent driven the car long enough to know if it was a faulty fpr...

being that the car is a return style fuel system i took the rubber boot off the return line due to it being corroded any ideas on what the issue could be

oh at full throttle the car is fine.

i did the test from the exhaust and the passenger side holds up the dollar bill but the drivers side doesnt keep the dollar bill up theres a popping in the exhaust.

the car does have hollowed resonators and a exhaust leak on the passenger side collector on the header

exhaust is

frpp shorties
bassani x-pipe
flowdisaster 3 chamber

check the tps. it should ohm out and then when you move the throttle to wot, the ohms should slowly(steadily)drop until its at wot

mystk96 · September 13th, 2010, 11:31 AM

mystk96 · September 13th, 2010, 04:08 PM

I used to have a friend with a mystic. That thing was BEAUTIFUL!!!!

When's the last time you seafoamed it? Seafoaming's the only way to clean the top end on b-ports (and no, fuel injector cleaner does NOT work).

If you haven't in a while, don't waste your time using it in the fuel or crankcase, just do the 1/3rd in the vacuum system.

mystk96 · September 15th, 2010, 04:45 PM

i did it a few months ago. do you think the carbon built up to much on the imrc's while it sat therefore didnt allow them to open to get the car to start

I see no problem.

Try cleaning the IAC. 90% of idle control is the IAC.

It can build up quick. I'd seafoam mine every other oilchange.

zdkel · September 15th, 2010, 06:37 PM

IMRC plates or were they deleted?

mystk96 · September 15th, 2010, 10:26 PM

honestly not sure wouldnt be suprised if they are deleted. is there a way to tell without taking the intake off

whty98 · September 17th, 2010, 02:16 PM

There is the control box with the cables attached, you can try to pull those cables. If no cables or control box, no IRMC.
