99 FORD Escort Check Engine Light Goes on and Off - No Code

check fuel pressure and timing

bbaclan,

I agree with checking the fuel pressure, because the problem could a failing fuel pump. The timing is monitored and adjusted (and readjusted) as needed via the ECM, so there is nothing for you to do or check in terms of the timing. Checking the fuel pressure requires the use of a fuel pressure gauge, and for us to help you further you gotta post the Static, Residual, and Running fuel pressure PSI values. You also gotta check for exhaust leaks and engine vacuum leaks. Exhaust leaks is a very strong possibility because, you said the entire exhaust system was replaced. Since the exhaust system was replaced, your problem could be a Catalytic Converter issue. The catalytic converter is a major part of the exhaust system. When the exhaust system was replaced can you remember if an OE converter was installed, or was a universal converter was installed?

Exhaust system was replaced from cat. converter back. (Front exhaust pipe w/flex - new H.D. Muffler - 1 tail spout - 2 HD clamps)

How much can I expect running fuel pressure diagnostics to cost? Obviously if it's a fuel pump issue I need to keep costs down as much as possible for a car that has a $200 value.

Honestly, the car engine runs really nicely except for the acceleration issue. It's great for my 18 yo to tool around town with. But is it worth the $700 fix of a fuel pump?

Also, I'd think they would have replaced Cat Converter if it seemed to be failing, no?
