Hey guys...

 

I've been having this weird problem for a while now...No matter what the speed, I can be backing out of a parking spot, going like 25 outta my neighborhood or cruising down the freeway but when I give my car about 1/4 throttle (on my boost gauge it's like 1/2 way between vacuum and 0 boost) it sorta misses and stumbles, like it's almost hurting for spark or air.

 

I have new NGK wires and plugs, my cap and rotor appear to be ok...I'm just wondering about my coil...I had an Accel and it died a few months back....Now I'm questioning the wiring of the new coil...How does it go...All black to one side, etc...

 

Would the coil being wired wrong cause my car to miss/stumble at only 1/4 throttle? Or could it be something else??? Maybe a vacuum leak, AAV, TPS?

 

Thanks,

Daniel

ihad same problem stock computer ovefueling at lower rpm's changed out o2 sensor and it went away

 

i really need to get brave and just switch over to my megasquirt just have 3 wires to connet and it will run of it.. sigh

Me thinks replace the O2 first...if not...then TPS.

Soo...Heh...Here's the fun part....Where can I find an o2 sensor for my car...Besides the dealer. Is the ea81t o2 the same as the ea81??? Or maybe the o2 sensor from an ea82t would work...Hmmmm

if you dont want OE...get the BOSCH OEM direct fit one from NAPA, autozone or whatever...I used the universal one as well. Both work great, but for $10 more, the OE style is just screw in, plug in, and go.

I have two EA82T powered vehicle, and both of them have a hesitation at low RPMs, I have tried everything to fix this problem, nothing ever completely got rid of it, so I live with it. My EJ20G (turbo) powered vehicle does not have any hesitation at any RPM, so it looks like Subaru fixed that problem on the EJ series turbos.

i put a old bosch heated 02 sensor i had lying around

 

came off a 88 saab 9000 turbo
