Hey everyone,I have a 2006 chevy malibu LT v the 2.2 4 cylinder and it has about 95K on it. Ns went to occupational like daily as I perform I noticed after job-related when ns went to shot to start my auto it had trouble starting. I tried the a pair more times and also it turn over yet the auto shaking and the inspect engine light was blinking it means something is serious wrong! i did a tiny research top top the matter I have had human being say it could be mine coil pack, spark plugs, O2 sensor, and also etc. Ns did have the spark plugs replaced back 4 months back so I know it couldn"t it is in that. Could anyone offer me some light ~ above what can be wrong?-Dan
Hey everyone,I have actually a 2006 chevy malibu LT with the 2.2 4 cylinder and it has around 95K ~ above it. I went to work-related like everyday as I execute I i found it after work-related when ns went to try to begin my auto it had trouble starting. Ns tried the a couple more times and also it turned over but the vehicle shaking and the examine engine light to be blinking it method something is serious wrong! ns did a small research top top the issue I have had human being say it can be mine coil pack, spark plugs, O2 sensor, and etc. I did have actually the spark plugs replaced earlier 4 months back so I recognize it couldn"t it is in that. Might anyone provide me some light top top what can be wrong?-Dan
Flashing CEL means there is a catalyst damaging event occuring, the misfire. Just because the spark plugs were changed doesn"t ascendancy them out together a cause. Brand-new doesn"t average good. There is no pulling the plugs or seeing what cylinder is misfiring the many or act both, there are many possibilities. Noþeles to carry out with spark, fuel delivery, even a poor catalytic converter might be leading to your problems. Those car had troubles with ignition coils and modules. Did you usage OE plugs or one aftermarket plug? Those cars were picky when it came to plugs. Probably shed two cylinders if it is ignition related to the coil or module. There are a couple bulletins that must be addressed if you finish up going down that road. O2 sensor won"t reason a difficult start, it"s ignored in open up loop.
I understand its a different car but my girlfriend has actually an 06 sebring and the inspect engine light to be blinking and also the automobile ran like total shit... Turned out she had 2 charred valves... 1500 bucks later it runs 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 come the part store morning to obtain the brand-new coil pack and also ICM. Perform you males recommend changing the boots ~ above the coil fill as well?? the a great thing ns left the car sitting and didn"t effort to journey it residence from work. That"s the last thing I desire to execute is have to replace a cat on height of a coil pack and also ICM. I will certainly let you guys know exactly how things go after I download the new parts!

I used to love Bosch plugs however no more. Too numerous problems with them. If castle aren"t fouled you deserve to see how it walk but before you get too much into it, swap them the end for ACDelco OE plugs. Boots, if they"re corroded, clearly degraded somehow, sure. If lock aren"t actual expensive, probably aren"t, it"s cheap insurance and also you"re right there anyway. Right listed below the generator is a big ground wire. Make certain it"s clean and tight.
I recommend that you don"t adjust parts based just on a wild guess.Please perform let united state know how it transforms out......and what the parts cost.Having that towed to a shop for a proper diagnosis might be cheaper in the lengthy run.
MalibuKen,I do arrangement having the password ran very first through the OBDII reader. Yet I have a very suspicion that it is the coil pack and also ICM. I have actually been looking through the internet and also a lot of people are having the trouble with these parts.
I understand where MK is comes from, however you only require a weak clues in that boot to enable spark to run to ground instead of across the plug gap. You"re almost at 100K, if the boots kit is 50 bucks, yeah maybe host off. If it"s 15 bucks, it"s cheap insurance that you shouldn"t need to pull the real estate again because that a while. Those coil and also module issues are pretty lot resolved i believe, at the very least we don"t check out a an excellent deal of lock anymore.
I recognize where MK is comes from, however you only need a weak clues in the boot to permit spark to run to ground instead of across the plug gap.
I was referring come the other parts the listed.I wholeheartedly agree that the boots need to be adjusted every time the plugs or wires are. Cheap insurance.

Well I thought the auto was working! I obtained the inspect engine irradiate again except this time its no blinking. The auto seems to it is in running it s okay no bad puttering. I also got the password of p0300 and p0420 as soon as i ran them v OBDII reader. I didn"t examine my spark plugs yet that is my following thing to do. Everyone have any ideas what rather this could be?? ns am hoping it isn"t the catalytic converter going!
Well I believed the car was working! I gained the examine engine irradiate again other than this time its no blinking. The automobile seems to it is in running okay no poor puttering. I also got the codes of p0300 and also p0420 as soon as i ran them with OBDII reader. Ns didn"t inspect my spark plugs however that is my next thing to do. Everyone have any kind of ideas what else this might be?? ns am hope it isn"t the catalytic converter going!
You got P0300 possibly due to the same reason as the P0420. You most likely only have actually code analysis ability, right? would certainly be quite to see misfire data so you knew i m sorry cylinders to be misfiring. If it has actually a most misfires ~ above 1 or 2 cylinders but very couple of or no one on the rest of the cylinders, I would say look at the impacted cylinders. If girlfriend have fairly equal numbers of misfires throughout all cylinders though, it might suggest too much backpressure together a aspect in the misfire. You might pull the O2 sensor prior to the cat out and also put a backpressure gauge in it and see if friend have too much backpressure. Spec is 1.25 psi
2500 rpm. Above that is restricted exhaust. If you have actually indication that restriction, then you reinstall the former O2 sensor, remove the post cat O2 sensor and do the same test v the same spec. If you still fail, the difficulty is rearward that the cat. If you are currently within spec, the trouble is the cat.
Sorry ns haven"t post in awhile. However here is the upgrade on mine car! So far I have replaced the spark plugs with acdelco, coil pack and ICM. I saw my mechanic he replaced the spark plugs from the bosche come acdelcos. He had said the very same thing you guys had actually written around the bosche plugs in my car. He cleared the codes and also said if the came ago on it can be the cat converter going on my car. So that came ago on today!! I uncovered online the there is a technical service bulletin for cat converters on my car. TSB 10134a extends my 8 year/ 80,000 mile to 10 year/ 120,000 miles. So I ultimately bit the bullet and took it come a gm dealer. I discussed the bulletin and what had been excellent to the car. So lets hope the comes back as a cat converter because that my car!!
So I found out that is the cat converter going! It will be extended 100% through chevy. They had actually the component in stock but they were absent a mounting bolt for this reason they bespeak it and my auto should be up and running ~ above thursday!!
