I know this is 4 videos and pics but i just bought a 93 GT and i have one little problem. the car has some sort of popping sound that sounds something like a miss fire from the spark plugs but i just did a full tune up and still when i accelerate it sound and feels like the car is choking and thats when it does the back firing sound so if anybody has any clue i would really appreciate your help thank:shrug::shrug::shrug:s

lean condition? :shrug: Plug Blowout?

 

[mymstngGT]

i just changed them

what are they gapped to?

fuel pump duty cycle?

 

[mymstngGT]

they r pre gapped already but someone had told me it could be my timing

detonating?

detonating?

yeah its like a little explosion

if you can hear it pinging, you better get that thing on a dyno. Could result in a big problem.

Have you changed your coil wires? stupid question.

to adjust things with access to tools and without going WOT a bunch of times where the cops can get to you.

I had a similar problem with my cobra while spraying nitrous. It would studder like it was backfiring or missing. weird.

are your plug wires in the right spot? i mixed up 2 of mine once, it sounded like a lil explosion n ran like shat

 

[mymstngGT]

ill have to check that out sounds like a good idea

did the car idle normal but when you would punch it it ran like you said "like shit"

is it popping through the intake or the exhaust????

could be a number of things....bad mass air,,,IAT....TPS..... etc...

aye man,i hade a similar problem.i bought a 92 5.0 mustang and when i first bought it, it idle good but when i stept on it,it choked up and ran like shit.It also backed fired. Also thought it just needed a full tune up and set the timing.Well i did all that and still the same problem.Got tired of it and started taking the motor apart,Happens to be a bent valve.So try checkin that on that by checking your piston compression.A normal compression will be 120 or higher.

i kinda thought so and hoped it wouldn't come 2 dat but is that hard to fix or what?

Back to basics; did you change the fuel filter? A clogged filter will starve the motor for fuel, causing a lean condition.

i actually bought it but haven't put it in yet, but ill do it asap

do a compression test...could be something in the head...hopefully not....

probably not a fuel filter issue....
