Bird of Prey 94
Registered User
I have a 94 Tbird SC and when I travel about 60-70 mph, the engine starts to idle rough and the CEL comes on. The car's speed will not go past 60 mph. I release the accelerator peddle, and a few second later CEL goes off and the engine behaves normal. The engine temp is fine, and the needle stays on the “N” of normal. Two weeks ago I changed the idle air control unit. I am not sure if it is the throttle position device, a dirty gas filter, or what. I am just not sure where to look. I need help.
