Ive replaced egr valve, cleaned tube from egr to intake, cleaned intake, took off and cleaned IACV, replaced front 02 sensor, and I have a stumble at 1000 to 2500 rpms on load in 3rd gear when accelerating mildly to conserve gas. this occurs when DECELERATING from 55 to 25 mph and then accelerating in third gear under load. Leaning towards fuel pressure. Could be fuel pressure regulater not responding to low vaccum upon low rpms.Or could be low volume. If I kick it down it accelerates fine. It also hesitates or stumbles lightly at a steady 55 mph. please help any info or input is appreciated. Also cleaned MAF with MAF sensor cleaner, even though it was spotless, new plugs, air filter and fuel filter.


thanks e-man

 

have you replaced fuel filter?

 

sounds fuel related like you said. When's the last time you changed your fuel filter or PCV?

 

had the same problem with my 96 when I first bought it, I replaced the fuel filter, cleaned the cone filter, MAF and TB. Solved! Could it be the fuel pump?
