Trick Tuners · January 30th, 2009, 06:47 PM

do you have any friends with a datalogger?

ModMustang97GT · January 30th, 2009, 06:54 PM

You checked your plug wires. If any of them or our coil are burned out or messed up, you could be getting a no-fire. The spark plug wire being messed up would result in a grounding of the spark hence the no fire. and if the plugs are going shitty enough, the miss fire will only happen when the spark gets ramped up enough with rpms.

edit ur tittle before a mod see's it

no cussing

jasons_98gt · January 30th, 2009, 07:02 PM

well all the plugs are firing clean the wires are only like 2 months old and the ignition coils are 2 months old as well nobody i know of with a data logger

ModMustang97GT · January 30th, 2009, 07:10 PM

Id still check the wires. If they are not in correctly, or are getting burned up, they could be miss firing.

The coil sounds like it wouldn't be the issue. can you tell if its miss firing, not firing, spark but no gas, or anything?

jasons_98gt · January 31st, 2009, 12:27 AM

its really hard to say honestly when it idles you can hear it mostly through the exhaust it has the purr to it then it sounds exactly like it would if someone coughed...then it starts purring again then it starts coughing and you can hear it up in the engine compartment as well....If im driving then come to a stop the idle starts jumping and the exhaust really breaks up then when i pull out sometimes i hit an occasional dead spot but on the highway it runs like a raped ape. It has tons of power pulls hills great. Just breaking up at idle

IAC Mabye?

jasons_98gt · January 31st, 2009, 12:53 AM

cleaned it it was still pretty shiny from the last time i cleaned it i also clean the egr valve and took the tb off and wiped the insides of that out as well

jasons_98gt · January 31st, 2009, 12:55 AM

i also bough a can of mass air flow cleaner and sprayed that as well didnt help either im wondering if i have a bad fuel injector the problem is that i never had a car reliable as this one and all of the sensors have 162k

cleaning iac/egr's doesnt work very well (not egr they dont work at idle, just thought I'd throw that in there) buy a new iac from ford (not parts store brand they are junk) if suspect.

jasons_98gt · January 31st, 2009, 01:24 AM

ok thanks im going to have to do more investigating i just hate to spend bux and replace to much shit and it not work

jasons_98gt · January 31st, 2009, 01:43 AM

think im going to pick up a new iac valve and a tps sensor

casper gt · January 31st, 2009, 01:47 AM

its not likely the tps. more likely the 160 themostat these cars dont like them at all ( tried one & mine not only ran like shit it cost me 2 tenths changed back between rounds & got the 2 back & never looked back)

jasons_98gt · January 31st, 2009, 02:01 AM

oh ok just though I'd throw that in there. I only run my car when the tracks open ( is it April yet?? ) but I've been using a 180 since that 160 episode with no problems.

97S281 · January 31st, 2009, 01:20 PM

Might sound retarded, but have you changed your fuel filter? Or cleaned your air filter?

jasons_98gt · January 31st, 2009, 02:38 PM

just cleaned my air filter last week and i put a new fuel filter on back in september

jasons_98gt · January 31st, 2009, 02:42 PM

i also put in a new pcv valve and ran some lucas injector clean my past few fill ups and didnt notice any change and unbolted the coil packs and cleaned them with a damp cloth to make sure they wasnt leaking at night
