[Entity34]

I'm gonna make this short and sweet and will answer all the questions.. 2001 2.4 cav. z24 35k o.e. miles.. ses light on.. code p0300 came up for a generic code for misc. missfires on all cylinders.. specially around 3k rpm.. and ses light flashes.. NO specific fault code.. At idle.. solid ses light on and cylinder number two missfire.. Replaced plugs, coil packs, boots at this time for no charge.. and the number 2 injector. Does not die.. and allways missfires.. Did not check out the ignition module yet.. but i don't know the specs on that.. can't see any vacuum leaks or hoses off.. New 02 senors.. cat convertor.. etc.. Mint car. Runs like poop.. Anyone else expierience the same thing before or can point me in the right direction.. Thanks Ronnie.

Hey man calm down. There hundreds of threads posted everyday. We cant get to all of them. Unforntually i dont know much about the 2.4L twin cam motor so i cant help you but dont worry some1 will.

[Entity34]

oh.. i'm calm.. it's just that my wife drives this car. I wouldn't drive a chevy personally.. But. From the posts i see so far.. Not much technical knowledge.. just the usual ricer stuff.. Don't want the wife to get stranded and gas is not cheap..

[Chevalier]

gas not cheap?..ahh where i am gas went down 65 cents since summer...id have to say thats cheap lol..

and right away come in a chevy forum and say u would not drive a chevy but want help..ehh?

and with that i get this..

[Chevy4life1985]

Well I think whats going to piss off the guys that not that shit is when he said " wouldn't drive a chevy personally.. But. From the posts i see so far.. Not much technical knowledge.. just the usual ricer stuff.. " Isnt going to help him.

Well if there was a hard fault code.. than i would.. as you can see in the first post.. there all generic codes.. no hardfaults at all.. so do not really point you in any specific direction..

[Entity34]

well either i pissed people off or i was right.. but still having the same problems any help besides. the throw parts at it would be helpful.. Again. no newbie to cars even our tech II did not point us in the right direction. If you don't know what a tech II is type those words in ebay.. Thanks. Ronnie..

[Ryan066]

heh .. you're some cocky... if your that good of a tech, with your fancy scanner.. then you should be able to fix it. good luck. and take your shitty attitude elsewhere bud.

Ryan.. i'm not gonna respond to you directly.. but.. All i'm saying is that my 12 techs that i manage can't figure this out with the techII and it's a 4k machine... so i'm looking for someone else that has had this problem before and may give me techs some knowledge and a slap in the face to prove them wrong.. thanks though ryan for your support. I appreciate it.

Shit dude, thats the way to get help! If this was posted on the Honda forum i'd be offended, but these Cavvy guys do kinda know whats up.....and you're not in the position to talk since you can't figure it out. Dont call people stupid because you're way fuckin stupider obviously....

i never called anyone stupid.. or anything of the sort. check out the top of the forum and work you way down... all i'm saying is this... help me out with the problem.. thats all.. i'm not superior.. never said i was.. i'm just telling the community that a gm 4k machine and my 12 techs cant figure it out.. so i thought i would post it up here.. period.. And as far as chevy. who cares.. my wife likes em and drives em.. her 97 200k miles had no problems.. but this one does.. Im not a fan of em. but thats not the issue here.. The issue is getting the problem solved for my wife. Thanks. Ronnie.

plugs, wires, dizzy, ECU, knock sensor, fuel map, bad injector, bad gas......did you check all those??

[Schister66]

maybe theres something in the cylinder that is getting hot and causing a misfire....carbon deposits.....
