Any suggestions on testing or pin pointing the issue? The codes it shows now are p0303 but the snap-on tool didn't show any cylinder misfiring currently. It also has p0117 and p0118 but thinking I fixed that with the new temp sensor. I suppose I should wipe them and see what comes up next. It also has a pending code of p0133...gtv237 wrote:Running issues with extended crank means it is running rich. Could be a problem with the ignition system, leaking fuel injectors or incorrect sensor reading.

Did you disconnect the negative battery cable after doing the work? That would reset the computer and it then needs to re-learn the best settings.
I picked up my vibe used with 140k miles on the clock and the first thing i did was install new plugs since i had a very slight miss. After new plugs, the car felt smoother but occasionally i still got a little miss. I pulled out my coil packs n noticed that the plastic boots that go down into the plug had very small cracks and sings of arcing so i cleaned them up and wrapped them with a quality electric tape and the issue went away.chopsieze wrote:Just swapped cyl 2 & 3 spark plug & COP.

What I found though is it's only misfiring on startup and a few seconds after. I used a live scanner to see it. I'm going to check into my fuel pressure and filter and see if maybe it doesn't have enough pressure during startup. Any other ideas what might be causing that?
Me too. None of the things you did cleared it up or moved the problem to another location.I think he is probably right.
Well, I concluded it was indeed a HG. Got a little worse, could smell coolant and see steam out of the exhaust yesterday, could smell exhaust in the radiator among quite a few other signs. Most of you are going to cringe but with the overall compression not being great in all cylinders and again, among several other issues with the car... I went cheap, since I couldn't pay a shop to put a new HG and I don't have time this summer to attempt myself, I tried some blue devil this afternoon. I haven't taken it on much of a test drive after going through the whole process but it isn't blowing white smoke anymore and also fires right up and no CEL or misfire in cyl 3. Just hoping to get a little more life out of it and hope nothing gets too gummed/clogged up from that stuff. I will post back in a few days.302LVR wrote:It does sound like a bad head gasket if the issue remains in that cylinder and especially if the coolant is mysteriously disappearing. Sounds like you might wanna do a radiator pressure test in which you pump air into the cooling system to simulate an overheat. Once you have between 13-16psi or whichever the radiator cap is rated for, you should notice coolant seeping out of somewhere. If indeed the problem is at cylinder #3 then i'm pretty sure you might have some coolant or rust residue on the spark plug electrode since the coolant is entering the cylinder chamber. If anything, try to bring cylinder #3 up to TDC when doing this and maybe shinning a flashlight through the spark plug hole to see if you see any green coolant over the piston. Also, you may wanna check your dipstick and see if your oil is mixing with coolant. If it is, it will probably look milky or like a coffee with milk type of mix. Good luck.
I get a lot of my stuff from Advance Auto... order online and use a 30-40% off coupon I find on the web and it's waiting for me at the store by the time I get there. Walk in, walk out. Easy to return then if necessary.Nevarnitsuj wrote:I'm getting 352. Was getting 351 but I moved my COP to 2 cyl. Anyone have issues buying a new COP. Amazon and rockauto said the part would fit but they are to fat and short. Anyone have a site I can use to get the correct size COP.
