hey iv done some research and iv see similar problems but not exactly like mine.

at start up with the motor warm or cold i get a rough idle for a few seconds and then it gos away plus the car kinda miss fires some time not all the time this problem happened from one second to the other. im pumping 93 oct, i put the heet bottle thinking it was water in the tank, i put the lucas injector cleaner. i don't know what else to do i have no warranty so no dealer suggestions. plus while driving normal no problem . while in hard driving the motor stalls out like if the car had no power or as if my tranny was slipping and also get some back fire. i just changed the spark plugs bout 2 to 3 weeks ago put in some ngk v power...

please help

 

all i have done to the car is intake, gutted cat, and the exhaust from the y back with greddy tip. those mods were done bout a year and a half ago and the nos is there but never used it yet. latest thing i did was the spark plugs ..

 

also changed to pcv n nothing i do hear a air leak somewhere around the the pcv i was thinking bout jus going ahead n putting a plenum spacer and new gaskets but did wanna waist the money for no reason

 

Cleaned the tb n maff today and still nothing

 

any one
