1996 Ford Aspire - Falls Flat With Acceleration

AMSKJRLAR · Post by **AMSKJRLAR** » Tue Aug 25, 2009 10:50 am

After replacing fuel pump and mass air - call still falls flat under acceleration. No engine light on. Idles good at times, stumbles & dies at times.
Removed O2 sensor, no difference. Any suggestions?

Why were fuel pump and mass air replaced?

There were no codes and most likely the cause, but did not fix

We can better guide you with the answers to a few tests...

What is the exhaust backpressure?
What are the fuel trims at idle and during the symptom?
Have you checked the timing?
What is the O2 reading during the symptom?

just a quickie here. when it's falling flat what happens if you spray carb cleaner into intake? anything beyond this without more information is a whitch hunt. unplug egr valve...................now i'm done.
