Ahhhh
 

im beginning to hate my car, this hesitation sux(only when flooring it, ezin' it runs fine!) im been reading other posts on this: im goin to replace my O2 sensor and fuel filter!! others say air filter, ports not opening right, secondaries, and grounds!!what grounds? cant be the secondaries cos it fine when ezin the throttle!! AHHHHH WTF!! out of the two accuators by the header the one closest to the firewall works properly the one closest to the fan is siezed!! could this be my problem? anyone!! help before i run this car off a bridge or something!! it just started doin this like a week ago!!

anyone want to buy a car, LOL!! Just kidding i just want this to go away!!

when and what is actually happening???

90% of the time when there is a hesitation it is related to poor grounds on the motor, battery, coils, alt, etc.

Did you read the FAQ?

this is happening at the dreaded 4000 rpm range, i read the FAQ, but not really sure the locations of all grounds!! could that seized accuator be the problem!!

i cant take this car anywhere cos nobody i know or in the area works on them, except Mazda at $80 p/hr!! BS thats a rip off

Sure a 5th/6th port not opening could cause the hesitation, but it wouldn't get any better at higher RPM

i just dont understand why ezin' the throttle would cos no hesitation then flooring it over 4000rpms!! this must be a fuel problem...............maybe?

screams bad engine grounds too me

ok then is there a specific area i should find most of them? the CPU is under the pass. side rug right?

The ECU is under the passengers foot panel, the CPU is mounted to the drivers kick panel. Two different buggers.

You will want to replace the engine grounds and battery ground first, then run a new ground for each coilpack if it still having problems, before messing with the ECU.

Use at least 8 awg wire for the engine grounds, but even 4 awg is better.

thanx man, i will do that tomorrow, got day off!! i will also replace the fuel filter and O2 sensor(i know that doesnt work the wire is BROKED!!) PEACE!!
