1997 Mustang GT Need your help pinning down a problem

jones450r · 08-15-2008

i have a 97 gt convertible the problem has been going on 4 a while now when i am driving sometimes if i get on the brakes and completely stop it SOMETIMES either dies or the idle drops and mostlyALL the time when i stop and shift my automatic 2 park it dies mostly but if it doesntthe idle drops way low and then picks back up. I have an aftermarket bbk throttle body which i just slapped on wout checking voltage, I personally think its the fuel pump(stock) but its not starving 4 fuel i dont think its really strong everywhere(i have new fuel filter and my car is well taken care of) or could it be my iac the only trouble codes off my programmer r o2 sensors. So please let me know what u think or if u have had a similar problem

if your having problems wth the O2's then I'd suggest replacing them wth a new set of oem Ford/Motorcraft O2's and sea if that helps......did you have this problem before the thrttlbdy swap?

no i dont think i was having the problems before the tb do u think that is the problem o i also have no converters

you might just need to adjust your idle screw....i just put a bbk on mine and it was doing the opposite and the rpms wouldn't come down. made a couple little turns to the screw and now its fine

o and i might have found the problem i checked my plugs and 3 or 4 of them had oil on them but i think i neen new valve cover gaskets but could this be the problem

It's an easy and cheap fix if that's your issue.
