1995 Cobra "Fuel or Exhaust Issue"
Love to read your posts and responses here. I have had my 95 Cobra Since 96 and love it, however It has lost half its power and can't breach the 3500 RPM mark anymore. I have replaced the plugs, fuel regulator, and fuel filter, air filter, O2 sensors, and airintake sensor. I am probably the poorest ot all Cobra owners so cost is a big issue here, but willing to spend thriftly to fix the right part.
I put a fuel pressure gauge on it and it was within limits but it was at the lower end of the scale. I pinched the return hose and the pressure shot up to twice the normal reading which the manual said was normal. However when I turned off the engine the pressure would not hold even with the new regulator. My question is, should I go with the pump or do you think the exhaust might have too much resistance to achieve the higher revs?
The engine idles fine and appears smooth but just stops at 3500rpm's. What should I try next?
Thanks for your help.
