Flashing CEL method there is a catalyst damaging occasion occuring, the misfire. Just since the spark plugs were changed doesn\"t ascendancy them out as a cause. Brand-new doesn\"t average good. There is no pulling the plugs or see what cylinder is misfiring the many or act both, there are lots of possibilities. Noþeles to perform with spark, fuel delivery, even a bad catalytic converter might be bring about your problems. Those cars had problems with ignition coils and also modules. Go you usage OE plugs or one aftermarket plug? Those cars to be picky as soon as it came to plugs. Probably lost two cylinders if that is ignition related to the coil or module. There room a couple bulletins that must be addressed if you end up going under that road. O2 sensor won\"t cause a tough start, it\"s ignored in open loop.
I understand its a different automobile but mine girlfriend has actually an 06 sebring and the examine engine light was blinking and the car ran like total shit... Turned out she had 2 scorched valves... 1500 bucks later it operation like brand-new again. I hope your difficulty isnt the server
Thanks because that the reply guys. Ns did use bosch aftermarket spark plugs. I\"m heading to the part store tomorrow to obtain the new coil pack and ICM. Carry out you men recommend an altering the boots top top the coil fill as well?? its a an excellent thing i left the auto sitting and also didn\"t effort to journey it home from work. That\"s the last thing I want to do is need to replace a cat on height of a coil pack and also ICM. I will certainly let you men know just how things seek I install the new parts!
Thanks for the reply guys. I did use bosch aftermarket spark plugs. I\"m heading come the part store morning to acquire the brand-new coil pack and ICM. Execute you men recommend transforming the boots on the coil pack as well?? its a great thing i left the auto sitting and didn\"t attempt to journey it residence from work. That\"s the last point I desire to do is have to replace a cat on top of coil pack and also ICM.
I supplied to love Bosch plugs however no more. Too numerous problems with them. If castle aren\"t fouled you can see just how it go but before you gain too far into it, swap them out for ACDelco OE plugs. Boots, if they\"re corroded, obviously degraded somehow, sure. If lock aren\"t genuine expensive, more than likely aren\"t, it\"s cheap insurance and also you\"re best there anyway. Right listed below the generator is a large ground wire. Make sure it\"s clean and tight.
I recommend the you don\"t readjust parts based only on a wild guess.Please carry out let us know exactly how it turns out......and what the parts cost.Having the towed to a shop because that a ideal diagnosis can be cheaper in the long run.
MalibuKen,I do setup having the password ran an initial through the OBDII reader. But I have actually a highly suspicion the it is the coil pack and ICM. I have actually been browsing through the internet and also a lot of human being are having the trouble with these parts.
I understand where MK is comes from, yet you only require a weak spot in that boot to allow spark to run to ground instead of throughout the plug gap. You\"re practically at 100K, if the boots kit is 50 bucks, yeah maybe hold off. If it\"s 15 bucks, it\"s cheap insurance that you shouldn\"t need to pull the housing again for a while. Those coil and also module issues are pretty much resolved i believe, at least we don\"t check out a great deal of lock anymore.
I recognize where MK is comes from, but you only need a weak point out in the boot to allow spark to jump to ground instead of throughout the plug gap.
I was referring come the various other parts the listed.I wholeheartedly agree the the boots have to be readjusted every time the plugs or wires are. Cheap insurance.

Well I believed the vehicle was working! I gained the check engine irradiate again except this time its no blinking. The automobile seems to it is in running it s okay no negative puttering. I additionally got the codes of p0300 and p0420 as soon as i ran them v OBDII reader. Ns didn\"t inspect my spark plugs however that is my following thing to do. Anyone have any type of ideas what rather this could be?? i am hoping it isn\"t the catalytic converter going!
Well I assumed the vehicle was working! I gained the examine engine irradiate again except this time its not blinking. The automobile seems to be running it s okay no bad puttering. I additionally got the codes of p0300 and also p0420 when i ran them with OBDII reader. Ns didn\"t check my spark plugs yet that is my next thing to do. Anyone have any kind of ideas what else this might be?? i am hope it isn\"t the catalytic converter going!
You got P0300 possibly as result of the same reason as the P0420. You probably only have actually code analysis ability, right? would be quite to view misfire data so girlfriend knew i m sorry cylinders were misfiring. If it has actually a most misfires top top 1 or 2 cylinders but very few or none on the rest of the cylinders, I would say look at the influenced cylinders. If girlfriend have relatively equal number of misfires across all cylinders though, it might suggest extreme backpressure together a factor in the misfire. You could pull the O2 sensor prior to the cat out and also put a backpressure gauge in it and also see if girlfriend have too much backpressure. Spec is 1.25 psi
2500 rpm. Above that is restricted exhaust. If you have indication of restriction, climate you reinstall the front O2 sensor, eliminate the post cat O2 sensor and also do the very same test v the same spec. If you still fail, the trouble is rearward of the cat. If you are now within spec, the trouble is the cat.
Sorry ns haven\"t posted in awhile. But here is the update on my car! So much I have actually replaced the spark plugs with acdelco, coil pack and ICM. I visited my mechanic he changed the spark plugs from the bosche to acdelcos. He had said the exact same thing girlfriend guys had actually written around the bosche plugs in mine car. He clearing the codes and also said if the came earlier on it could be the cat converter walking on my car. So it came back on today!! I found online the there is a technical business bulletin for cat converters on my car. TSB 10134a extends mine 8 year/ 80,000 mile to 10 year/ 120,000 miles. For this reason I ultimately bit the bullet and also took it to a gm dealer. I pointed out the bulletin and what had been excellent to the car. So allows hope the comes back as a cat converter for my car!!
So I uncovered out it is the cat converter going! It will be extended 100% by chevy. They had the component in stock yet they were missing a mounting bolt for this reason they bespeak it and my car should it is in up and also running top top thursday!!
