These codes pop up every once in awhile... mainly when i start the car or am sitting at a stop light

I have changed the plugs but still get P0300 Random/Multiple cylinder misfire detected


not sure what this means. or how to fix it... P0315 Crankshaft Position System Variation not learned

not sure how to fix this.... P0496 EVAP Emission High Purge Flow Fault


any help would be appreiciated THANKS

 

have you ever put a engine in it or changed the sensor or put a ecm or battery in or un hooked the battery for long part of time

about the evap purge valve. check connections and if its connected, prob bad purge valve.

 

changed out ecm from stage two to stage three. when i bought the car about eight months ago it was stage two setup and he had a stage three zzp ecu and 60's and all that so i switched to stage three about three weeks ago as far as the evap system goes i will admit i know nothing about it

 

About the crank senssor, did you ever do a crank relarn? About the purge valve, look ontop the valve cover when looking at the engine itll be on the right hand side of valve cover, it has a black tube not vacum line but a black tube that will be the purge valve. check connection and so forth about the random misfire check coils plugs and harness for the ignition, our sc cars always shoot the p0300 code just because the lsj thinks its cool lol. no but check everything.

 

no no crank re learn didnt know i had to

 

well if you change ecu, yeah of course, you disconnect battery from system for some time yeah, you flash the ecu i would just in case. with hp tuners you dont have to but i still do each time i flash my car . so what all did you change this last time?

 

are you on meth? I ask cause I saw your running a 2.6

 

i used to be on meth. lol not the drug ha ha ha ha ha. I got rid of it because my iats are fine and i care about my motor so i am only running 19 degrees of timing. the eway i ported my blower makes me get about 16-18 lbs at most and my iat2s are great unless i over due it, by to many runs .. Tuning for meth is easy as long as there is nothing wrong with the car like bad ic pump and so forth, i was tuned for it when i was stock, jsut with a tune and meth and exaust and intake i ran it with the 2.6 and i liked it but ported my blower. Like i said tho it is different then wut every one lese does... and i was running full 100$ meth also, another reason i got rid of it was because i got tired of buying the dam* shi*.... so are you tuned for meth?

 

100% meth you mean? Ya thats what I run, I have a speciality fuel station by my parents house its called purvis, its 4 bucks a gallon.

 

Yeah I actually would by a 5 gallon bucket at like lowes or home depot if they had it. I used the arm meth kit......



So have u got ure codes figured out?
