Take it to Auto Zone for a free engine code reading. They'll be able to tell you exactly why it's on. Sometimes it's even because your fuel cap isn't on all the way.

carbon build up in your intake ,,pour 1 entire can of Sea Foam in your gas and 6 ounces in your oil to allow this fast acting solution to burn that gum and carbon as well as moisture completely out ,,change your oil about the 400 mile mark as those broke down carbons and **** is in your oil ,,,you will be running smooth ..do not worry about that exhaust being smoked up ,,it will clear in 30 minutes or less...also after ,,,check your engines coil or coils and or distributor

Car running lean on bank 2, changed intake gaskets and pcv valve


what does exhaust smell like you may have carbon build up in engine try removing o2 sensors and cleaning with brake clean and reinstalling reset code and see if it comes back and how long it takes to reset also you can put a can of berryman in the gas tank with at least 1/2 tank of gas or more also buy a can of sea foam and install through vacuum booster hose you may see lots of black smoke from tail pipe if so after following instructions for application drive some what hard and if the black smoke continues fore at least a mile keep driving and if you notice a diff in runability but still have a little black smoke buy another can of sea foam and repeat service NAPA has sea foam on sale this month

12 miles a gallon.. Put on new thrmostat


a few things you can do is replace the fuel filter, air filter, and do a thorough injection cleaning. you can do this simply by buying a can of sea foam from any auto store and turn the car on and pull out a brake booster hose. this is located under the hood in the top right. it should be black, big and circle. also two hoses should come out of it. slowly pour the seafoam in. try your best to keep it running. once it starts bogging down, stop for a second then keep adding. do about a half a can and pour the other half in your fuel tank. turn the car off for about 5-10 minutes and then start it. lots of smoke will come from your tailpipe, but thats okay because that is all that carbon build up. and you should notice more gas mileage!

2002 toyota camery will not idle. after i replaced air filter, but it returned by itself. that's been about 5,000 miles ago, now it's back. also, i had the battery checked also and they same it was running...


This is ironic. I am on hear searching because the same thing happen to me today. replaced the battery and was having the smae idle issues. After a few hours of investigating and looking for air leaks we ended up with the intake into the throttle body housing loose and found alot of build up in the throttle body housing. Cleaned it out with carb spray and problem seems to have gone away for now. Not sure if this helps but this is where I am so far. Also check engine light was on and the tech erased it after cleaning and it has not come back on. Code was for mass air flow sensor and I originally tried a new one and it didn't change anything until I cleaned the carbon build up in the throttle body housing.

1987 toyota 22r truck surges after idleing while


Just off the top of my head, guesses: Given what you've already done and the high mileage, could be carb, but I'd start with fuel filter and a good additive like Sea Foam. Also, you might want to replace the PCV and any other sensors which may be suspect.

Getting terrible gas milage. only 25 mpg!!


sorry but if you think the plugs are wrong then you are a sunday mechanic and this sort of problem if its electrical will be above your head,check colour of spark plugs and if blackish clean out the air filter,are the brakes binding ??if not and the air filter is clean then run car into local garage,could be anything from low compression caused by worn valve seats to broken piston rings
