this thing does not want to rev to redline...the cel flashes when i try it feels as if the cam will not switch over but...that may not be it....i did just fill up last night and today this started...could i have got bad gas? runs fine below 5K does not fuel cut ...also might i have a bad plug or ignition coil...cant get it to throw a hard code it just flashes afraid to stay at 5K+ for too long....im gonna check the front three plugs tonight

 

are you talking about revving the engine while the car is in park or nuetral? Because I don't think the car will let you rev it to redline unless you are in gear. It's a safety thing. At least that's what I've always thought. Anyone else?

 

i had similar problems this weekend, i'm gonna get it scanned tommorw

 

well sorta good news...i check my front 3 plugs...they look good...sorta whiteish brown and messed with the connection on my uni chip,still nothing but i did throw a hard code right away so...tomorrow ill have it read and no better where to look...funny this happened right after the fill up...if i filled up with less than super (not by my fault) WOULD THIS SYMPTOM FIT?

 

Bad gas won't cause the car to to flash the MIL.... does it re-limit at 5K? A faulty cam position or crank position is usually the cause for this... although the crank position sensor will put a rev-limit at 2K RPMs.

Re-check all the connections for the Unichip etc... which is probably the culprit!

 

no rev limit at 5 k and checked oil tomorrow ill read the code...it may be the uni chip ...but...it wasnt touched really since this happened...i say this because i did tuck some of the wires under the carpet last time my wife drove with me which was just a few days ago ,and when i went to pull the switches back out i had a hard time telling which end to pull...so could be the culprit

 

random multiple misfires in all cylinders,plus possible ignition system...i guess what im asking here is if my gas station sold me gas that was labled 93 but was really 89 or even 87 could i get these symptoms? wouldnt the lower oct gas detonate under load?

 

I thought you said there was no DTC? Random multiple misfires could be a gas issue... but also could be some loose connection with the Unichip if it is persistent. Try better gas and reset the DTC's.

 

at first there wasnt but after i checked the plugs last night it threw the hard code...this showed up right after the fill up...bad news is i have 3/4s of a tank...anything i could add to bring what there upto a higher octane? teulene? how much to 10 gallons?

 

added 3 gals of 108 to 10 + of what ever i have in there...still no change ...if my battery were dead ? i do have a tractor battery in there has been for 10 months...every thing works car starts...windows lights ect...
