mayday i got a problem.ok i was driving today on the freeway i smell something burning from under the hood.then all sudden my CEL came on???i kept driving til i hit exit..then pull up to a park spot shut the engine to let it cooled.look under the hood..saw lil smoke evaporate from where the head gasket/timing belt area is..and the fan were still running for a good of 10min.i waited for the car to cooled down then start it back up..i get no CEL now??what can be the problem??

 

Were you watching your temp gauge??? Was it overheating?

I would start by pressure testing the cooling system and see whatcha find.

If it's that bad, you should be able to see something

 

is not over heating or anything.looks like smoking from oil under the hood.it idle at 700-800 is this normal?sometime it kinda shake/bogs lil when idle that low and picks back up again.i cannot adjust the idle cause the ajdust is on there to tight.

 

today i started it up..check..cooling system are good.only thing is car bogs lil then goes ritght to normal..now i'm not gettin no cel wtf??how can i tell if the headgasket is bad??can it be bad headgasket??help

 

i had the same problem

check the o rings for you spark plugs
mine were all dried and the burning oil get outragous

 

damn..i was driving down the streets to the store today and there you go same problem happen??i'am going to check the spark to see if it's the hg.and i'm gettin some small leaks around the oil pan...ideas? this kinda problem is making me want to sell the car..help

 

i look at the motor today.looks like valve cover gasket has small leaks.starts up the car let it run for a good of 5min.why is my idle doin the bouncein up to 2200rpm then drop back to 1000rpm even when i gas it it won't stop.how do i fix this problem...the motor is f22a4..need help asap

 

ur valve cover leaking wouldnt set the CEL off. lol. and the idle proble is most likely a vacuum leak. id have to look at ur car. cant really guess. make pictures or a video.

 

If your gauge is telling you it's not overheating and it appears to be running fine (by fine I mean no serious overheating during drive time) than I would guess a valve cover gasket. Make sure that their is no oil leaking on to your lower exhaust manifold (that may be where your smoke is truly coming from).

If it were a bad head gasket...you would know. You car would be smoking white smoke like it had emphizema.

White smoke---> Condensation problems i.e. bad head gasket, cracked head, or cracked block
Black Smoke---> Fuel system problems i.e. too much gas and not enough air
Blue Smoke---> Worn out engine

 

i think is #1 or #2 as describe.today the idle was doing the butterfly while i was driving and my temp went all the way up to Hot almost overheated on me.. i had to park the car to let it cooled down..after that i added some antifreeze and everything went good.weird?i need to fix this asap??already check vacuum and clean out the air control.

 

I hate over heating cars....bastards.

Ok, we'll, in all honesty I would have to say that your wierd idleing (rpm's wise) is directly related to your over heating. Your car could be running way too hot, stressing the motor way to much, and therefore causing bad idle. What I would recommend is doing a full coolent flush and if nessesary flush your oil as well. I ran into some OEM parts that needed to be replaced a while back and messed with my heating. I had terrible idle and the car wouldn't be able to go 2mins without completly over heating. I replaced my coolant and oil (extreme heat broke it down). After that, my baby was running better than before

 

ya look if you are getting any smoke out the exhaust first.

change your oil and see if any coolant comes out ( coolant will come out before the oil from the drain plug)

the weird idle i agree sounds like a vacuum leak.

the oil pan leaking is a very common problem, that is nothing to worry about as long as it is not leaving oil spots in your driveway. basically just check your oil level on like every other time you fuel your car(it is good practice anyway)

If your coolant was low, do yourself a favor, and find a friend that has a coolant system pressurizer, if it is an external leak it will show its ugly head with 15psi of pressure, but DON'T exceed 15psi, exceeding that could cause damage to your cooling system.
