" edit: problem is finally fixed. bad opti connection.
just took the car out for a N/A pass. it pulled better then i can ever remember. then did a 60 shot, and for the first time i got to see what nitrous was supposed to feel like. "



for the last year i have been having issues with my car. missing while the SES was on, or just before it. at WOT it had a miss that got worse and worse. idle choppy at times, mostly after the car got up to temp.
PO100 was the code i have been getting. i thought i traced it down to the harness. bought a new one, code went problems stayed.
that was last week. so over the last week i have been checking into things. pulled a few plugs, found one that the strap had broke off and the plug took about 5 turns by hand to come out. so i THOUGHT that was my issue. replaced it, nope. stayed the same but seemed to idle a lil better and cruise smoother.
so tomorrow i planned on taking it to a mech cuz i had given up. but before i took it there, i knew the only other problem was the driver side header gasket. so i wanted to fix that so they could not say that was the problem, and i walk out of there with a lighter wallet and same problem. so i fixed the gasket, sweet no more ticking. no code. car still ran the same.
plan is still take it to mech tomorrow.
go play poker, lost that. and on the way home it acting up at cruising, idle, acceleration. WTF. then the SES lights comes on. damnit.
so i get home ( its dark out mind you) and i wanted to see if maybe my bolts backed out of the head. leave the car running, pop the hood. i thought i heard an exhaust leak. but once the hood was open i seen the culprit.
spark was arcing. the first plug on the driver side and there was some under the coil/ above opti, couldnt tell exactly where it was coming from.
so the bad arc on the plug, coming out of the plug wire seemed like it didnt want to go in the spark plug. but around it and into the head. weird. it was just a straight erratic jolt about an inch long. then the others were just small ones near the coil.
so what is my problem here? do i not have the wire boot on the plug correctly? i did not use any antiseize. these are the taylor cut to fit OTVC.
suggestions?
in the daytime how do i find where the ones near the coil are coming from?
thanks in advance.

 

Ya need to check ALL the plugs first before paying to have it done.

 

well tomorrow i am going to see what is going on with the plug arcing on the driver side and near the coil.
i will take your advice and also check the other 4 plugs.
after that is done, and if i am still having problems, then it is off to mech.

 

There would be 8 / eight plugs to check not just the other 4 / four.. If it's only the plugs ya can put a new set in.
The first thing the mechanic is going to do is pull the plugs.

 

I had issues with Taylor cut-to-fit wires as well. The heat from the headers just ruined the set I put on. They became brittle and started cracking, even on the plug boots. I replaced them with Accel Extreme 9000 wires (with Taylor fire sleeves on the boots) and have had no problems since.

i have been having this same problem choppy idling trouble shifting while accelerating.....it goes away and come back off and on....im gonna try a tanny flush....

 

well it was monday that i pulled 4 plugs, that i why i said pull the other 4 tomorrow.
so u think still think i should pull them?

this is my 3rd set of taylors, just my first for OTVC. the prefit ones just ended up on the headers after a couple hundred miles. that is why i am trying these now. seem to be working good. where they are closest to the header they are not colored or showing any signs of heat.

 

the plug that i was having problems with, i pulled out first. (with the arcing) at first glance it looked fine, then once i took it out of the socket all of the ceramic started dropping out. the ceramic was cracked and falling apart!
what would the reason for this be?

well going back out to pull the rest.
edit:
well got done pulling them all. seemed to be fine cept for 2 on the pass side werent fully colored? is that to any significance?
ok pulled the wires off the opti too. well the one that was arcing on the plug ( that i also seen arcing under the coil area, but really couldnt pin point it) i think i know where that coming from also. when i pulled that one off it just slide right off, no clicks or restraint. put it back on and no clicks. looked inside the wire and the connector part didnt seem small enough to make the connection. so took one of the other wires and made sure that it wasnt the opti putput. and this wire clicked 3 times on it. so i knew it was the wire that was problem.
luckily i had an old wire that was still in good condition and put that one on.

so from what i could say as of right now, i believe my plugs and wires should be up to par. so if they are any more ignition/spark problems atleast they are ruled out. havent driven the car yet to say if the problem is solved though.
