Just bought a 88 shelby z daytona with a 2.2 turbo. it runs but does not like to go over 2000-2500rpm. comp says 51...map sensor but the previous owner said it was replaced(could be O2 also). If you give it too much gas it wants to die. Any suggestions? Im going to try to fix it so I can drive it w/in the next week so please let me know ASAP.

 

correction...sputters at 3000-3500 rpm...if i give it too much gas it starts to run rough and have no power. Any suggestions would be helpful.

 

I just went through somthing like that with my daytona what mine was doing was anything over about 9pounds it would run awfull and fall on its face and what I did was replaced the o2 sensor, map sensor and made sure the computer was good.

 

I took it in for a diagnostic and they said the fuel pump didnt provide enough pressure and the fuel filter is clogged. I think when the last fuel pumpo was put on it wasnt done properly, so I bought a new pump assembly and filter(lifetime guarentee on it) and will be putting it in today along with probably doing the rear brakes. As for other problems...the diagnostic showed everything to be fine except the pump and filter, but I have a problem with the radio also. The radio flashes and makes a boing noise when it is turned on and otherwise does not work. If I canty find the problem I will most likely switch radios. AND the odometer does not work...more fun.
