its a 94 mustang gt with what i think is a E303 cam and ford racing roller rockers and gt 40 intake mani and adjustable fuel pressure regulator with external gauge. i bought it with all these mods but it seems like when i first start it from a cold start every thing is sloppy. at idle it sounds like its camming big time and when i drive it the throttle response is a little off. after 10 minutes of driving it it will be good and instant throttle response. and it also has bbk 75mm throttle body.


i let the car idle 15 minutes today after siting for a week and i did a burn out and holding it in 1st gear i usually keep it at quarter throttle but today i kept it floored in 1st and was siting at 4800 rpms and sounded and felt like it was miss firing.


What could be my problem?

also the 02 sensors are disconnected.

Your car has no way of learning an adaptive strategy with the o2's unhooked, its running off base timing and fuel tables. need to hook those up.

I was thinking about that also. but the connectors are all chewed up and wont plug into each other. what should i do?

[89coupe]

New connectors and wire it up

[TravisCadello]

is the junk yard good place to get em?

[89coupe]

If its the 02 harness itself, just go to the junkyard. But make sure its for your car. IOW, manual trans and auto trans are different.

Definitely, get those hooked back up.

its just the clips that are messed up.
