Buddy having trouble with his daytona...

[94NDTA]

My buddy had a pretty nice 89 Shelby Daytona with Foward Motion Inc Enforcer II 2.2 with a stage 2 head, stock turbo (for now) stock injectors, 255 fuel pump, adjustable pressure regulator, Full 3 inch exahaust w/dp, very large aftermarket intercooler, and the stock computer untouched.

Now, I know a little about cars, but I usually work on modern SBC's, and SC'd 3800's.

The car is in limpin mode all the time. We check the plugs and plug wires many times, and to the best of our knowledge it is hooked up right. His father was a Chrysler mechanic back in the 80's and 90's and rebuilds chrysler trannies for a living, he said it is hooked up correctly.

Now, here is my concern.

A: is the computer fried?

or

B: Being that he has a different head and cam, doesn't the computer need to be adjusted for this?

If you have any other ideas as to what it could be, let me know. I want him to get this beast on the road so I have some competition.

if the computer is in limp in mode I assume the Check engine light is on. Have you checked the codes to find out what's causing it? Turn the ignition key on 3 times. On the 3rd time leave it on and count the flashes. aka. Flash long pause flash-flash is code 12. which is battery disconnected within so may key cycles. Check MiniMopar Resources for a better description and a list of all the codes.

Not necessarily. I am running a stock computer with a high-profile cam, and my car is not in limp-in mode.

Check for fault codes. If the car is indeed in limp-in mode, there would be a code stored.
