Wires, your spark plug wires, i changed mine and it bogged, try using high octane, when i put new ones in it bogged but now its fine...could be strong of a spark not high enough octane idunno. All im saying is that it happened to me but stopped a short while after i installed MS so cant help ya out there.

 

ive ran 93 octane in the car since i started driving it (roughly year and a half ago)

thanks for the suggestions though i appreciate the help.

 

clogged cat.

 

clogged cat explains the poppy sound from under the hood when pinned at WOT and all the hesitation problems along with the bogging down and misfiring?

 

unbolt the cat and find out.

 

It definately does.

 

 

ok im gonna check in the morning to see if the cat is clogged....

what causes it to be clogged just running rich or something else?

also i do not have EGR anymore its been sealed off dont know exactly what type of effect that might have on a cat converter except maybe not make things run as rich?

 

I checked the ECU pin 2I-Igniter
and its WAYYYY above spec numbers

Spec:
Ign switch on- Below .5v
Idle-Approx. 1v

My Readings:
Ign switch on-10.2x
Idle-11.6x

Bad ground? if so which 1 to check?

 

ive re-grounded ALL my engine grounds
checked for continuity on all of them
all my ECU pin voltage's are good EXCEPT the 2I (Igniter) which is supposed to be approx. 1v at idle and im showing 11.6 at idle
and i am throwing a #1 code which is Igniter Signal

plugs/wires good
CAS good
MAF good
coil pack good

in the morning im going to peel open the ignition harness (if thats what you want to call it) and start looking for a damaged wire because high voltage on those Igniter connectors tell me that there is low resistance/bad ground but the grounds all across the motor are FINE and checked out good with good reading so my guess is bad contact inside the harness somewhere. sound like im headed in the right direction to you?

 

cat is not clogged...
pulled the ignition harness today and saw no damaged wires in it everything is intact no loose connections...still no problem solved...what else do i need to test?

checked voltage on the ECU constant grounds (2A,2B,2C,2D) got approx .01v on those which i didnt think too substantial sounded about right?

still getting unsually high voltage from the igniter pin

 

Put a timing light on it just to be sure and post your numbers. The more you post the more likely someone here will have an answer. Mine skipped timing and had serious bogging. I've also had bad wires and got bogging. FYI: When timing was off I got all sorts of codes none of which indicated timing.

 

if you are having ignition issues this severe you will likely need a new cat by the time you debug the whole thing. I'd recommend getting a new ignitor as it sounds like this one is hosed.

 

1.8 igniter is built into the coil pack correct?

 

Yes 1.8 coils have built in ignitors. 80% sure anyway. I know all NBs do.

 

and i replaced the coil pack so i dont think its a "bad ignitor"

 

did we check the FPR yet?

 

Keep us updated.

I still got dibs on timing.

 

why would he check something when u clearly labelled ur first response with "EASY one. its ur FPR"?

he said his fuel pump and filter were a year old but im guessing he didnt even bother to check like you told him to.

 

more info for you guys...
the problem he is having gets worse when its raining...
I still think its electrical especialy after that fact
