Hi All,
Well I finally replaced the exhaust on my 1985 Mustang GT. I went from the old stock system to the following:
Flowtech headers (Equal length long tubes) Flowtech Off-Road H pipe American Thunder Cat-back system from Flowmaster
The sound is phenominal! Now the only problem which I have now are the following:
-idles at 1,000RPM instead of 800RPM
-At highway speeds of about 120KM/H it starts to chug like it's not getting enough gas or something and I have to either downshift or slow to 100KM/H. It then smooths out but it feels like she is hesitating.
-Seems like the engine is shaking sometimes when I am idling. Is this normal?
So can anybody please help me with what is happening? Carb adjustment needed or what?????
BTW I have brand new plugs, edelbrock air filter, and 9mm Ford Wires and fresh oil.
Its a 5spd.
Please help.
