alright first off im new to these forums, but im finally glad i chose one to post on, haha.

okay i wouldnt start off by asking questions but its becoming a hassle not being able to drive far..

i have a 1988 GT, when the weather is hot outside, after the car warms up after about 45mins of driving the rpms will bog(from about1100 down to 500-400), and when you hit the gas, the engine makes like an airy sound and doesnt raise rpms,the only thing i can do is shut the car off wait a second and restart which will let me run the car maybe 5 mins longer.
i have a clip of the car dying,

heres a link to a video i have.

the quality isnt great as youtube shows in landscape and i took the video in portrait on my iphone but you can hear well enough.

and heres a list of parts ive replaced trying to fix..
Spark plugs, wires, ECT engine coolant temperature sensor, Temperature control switch, ICM ignition control module, i have alse cleaned the IAC with no success.



can you help.. please?

When the RPM is low and starting to bog, do you have a fuel pressure gauge that you can check the fuel pressure with?

Id look there. Also, what about your coil? No CEL?

You should try replacing the IAC. Cleaning rarely works.
