I own a shop, and you should check the oil sending unit, as they are bad to get cracked, and/or break causing a pretty bad leak. Check the valve covers, and more importantly, check the PVC to make sure it has enough vacuum on it, as it could be plugged up with carbon and not have any vacuum on it. Put a new PVC valve in it, as that will help. When an engine is allowed to build up pressure inside, it will push oil right past all the seals & gaskets, and on to the ground. We find a leak by wiping down the entire engine, or using an engine cleaner, and putting it on a rack with it running. That way we can see where the leaks are, and determine what to do to fix them. Glad to help out, Good luck!!!

My 95 Landcruiser with 1FZ-FE engine runs but misses very badly, will not idle.


Sounds like a vacuum leak.

Search for it VERY CAREFULLY by spraying a shot of carb cleaner here and there. When it revs up or smooths out, you'll have located the leak.

Keep a fire extinguisher handy when doing this, and don't spray into electrical parts like the alternator or distributor!

Took my focus 2003 to autozone it is going thru alot of gas and we changed the spark plugs they ran a test and the codes are po113 & po303 i do not know what this means can you help me


P0113 indicates the IAT Intake Temperature Sensor has a problem.
P0303 indicates a misfire on cylinder 3

I believe the IAT is built into the MAF sensor located in the air snorkle and helps regulate the air/fuel mixture. Also concentrate on cylinder 3 looking for problems such as injector, wiring, etc.

Hope this helps!

Buick review


Good engine 28 mpg+ hwy. These 3800 engines had upper intake problems and would leak coolant into the combustion chamber. The new ones were re-designed and do not give any trouble. My 90 buick 3800 has 295000 miles on it. If yours is supercharged it does not have that intake problem.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

IAT means Intake Air Temp sensor. O2 is reffering to the Oxygen sensor. These are two different sensors on your vehicle. These perform different functions.
