Sounds like you have water in the oil which means you could have a blown head gasket. Can you tell what got in the oil. Is it antifreeze or gas. If gas you probably have a injector sticking open.

SOURCE: Check engine light

dear friend-what i can pick up from your explenation and the fault code is that your intake air pressure sensor is at fault.the smoke from the back of your was because the ecu requested more feul and thats why the smoke.feul cosumption will increase every time this light comes on

SOURCE: 2002 kia rio rxv check engine light came on again..

On my wife's car the mechanic said it was gas cap. (NOT!!) I cleared with an OBD reader and the code suggested a leak in the evatorator system. I found a steel tube that was routed over the weld flange of the gas tank. It went from the front of the car, down the drivers side, over the weld joing of the gas tank and into a charcoal evaporator filter on the passengers side near the rear wheel. The tube crossing over the gas tank crumbled when I touched it. I replaced it with a short piece of reinforced neoprene hose (to cross over the gas tank) and a couple of hose clamps. Cost of parts was about $5.00. Havn't seen Check Engine since. Good luck

Heater blowing cold air


1: Check that your radiator isn't low on water and anti-freeze
2: If your radiator level is OK then you may need to replace
the thermostat.

Volvo s70, 1998, heater not blowing hot air


Are you getting coolant flow through the heater core? These cars have common problems with heater cores but they are easy to replace. IPD has a Video on U-Tube with step by step instructions. Also if you are in very cold weather have you checked your anti-freeze? I saw a Toyota last year freeze completely because of no anti-freeze. It took days to thaw out the heater core and they were lucky that the ice did not blow it apart. It took me hours of starting it and running up to a low temp and shutting it down to get it drivable.

1995 Audi 90 runs hot, blows sometimes hot and sometimes cold air


check anti-freeze level if you have a slow leak and level is low the heater core wont have fluid enough to supply the heat as fan blows through it and would also explain running hot if thats good have thermostat checked and changed for a lesser temp. shouldnt cost more than 25 parts and 1 hr shop time

2002 Buick LeSabre Custom. Cooling System had brown chiffon looking foam in radiator. Drained and flushed cooling system with water. Disconnected both heater hoses and forced water through in both...


The brown looking chiffon could be oil in the water. However, if you are sure the system is ok then I would check the actuator door motor on the heater and make sure it is allowing the heat into the car. Seems as if you have done as much as you can.

What does it mean if your heater is blowing out cold air? Help I'm freezing! 97 buick lesabre


I have a 2000 having the same problem. Repair shops want almost $200 to look at it before determining the actual problem. If the heater box has to be removed, the mechanic said expect a bill of ~$600 or more.
I hope you find a solution that is more reasonable. I will keep monitoring your link.

Heater blows cold, temp gauge rises 1997 Camaro Z28, 50,000 miles...Florida, freezing in NJ Car just started blowing cold air today...always smeeled anitfreeze...always has water level light on as long as...


heater core is probably what was changed,..a little radiator under the dash that the hot water runs through and a fan behind it to blow at it thus giving you heat,...pretty much thats it in a nutshell,...sounds like something still leaking under there, (anti-freeze smell),... fill it back up with anti-freeze (non-toxic type so you don't polute) and drive to where you gotta go,....go to your mechanic to find that leak,.good luck, and do a hole shot for me! thanks, cracklin joe

Heater is blowing cold air. Could it be that my


Had similar problem. The actuator that opens & closes the air blend door quit working. This is easy to see if you remove glove box. The actuator will move when you adjust the temp selector (do this while the heater is running).
