the owner of the car should check on the carburetor of the car .The owner of the car should be able to service carburetor.Prepare the equipment or tools in servicing the carburetor .So that when the carburetor will be repaired or service no parts will be damage or lost. Locate the carburetor ,disconnect fuel lines accelerator cable and magnetic jet from the carburetor, Dis-assemble the carburetor ,clean the carburetor with carburetor cleaner, observe safety measures. but if the owner of the car don't have time in servicing the carburetor. then owner of the car is advice to go to a car shop mechanic and let the car mechanic to do the job.

Change fuel filter, air filter and if that doesnt help check fuel pump pressure.

Did you ever find one I also need one

This could be a grounding problem. Check all battery connections. Also check motor to body ground strap for corrosion. Check battery to motor ground and battery to body ground. Even if the ground looks allright it can be corroder underneath, so you have to take the ground bolt off to clean it.

mcdevito75 here, Waterpump will not cause over heating unless it is leaking prestone., First make sure you have radiator full of prestone, mixture of prestone on the prestone package, usually 50% prestone and 50% percent water. Most auto parts stores have a gauge you can buy to check the prestone mixture. Overheating can be a faulty thermostat, if yours has not been changed in 2 years, chaange it to a 180 degree thermostat. Also make sure all belts on the engine are adjusted, power steering, alternator, etc as a general rule 1/2 inch play in each belt connected between each pully.

Check other end from air cleaner duct, where it hooks to the throttle body, some thing could have gotten stuck in there, holding the flap open some what making it idle high.

check fluid level of coolant, thermostate, and fan.

Flush system and install new antifreeze.

fan doesnt come on ????
thermostat upside down ?

bad temp sensor for fan

You can chance moving it in your driveway very quickly if absolutely necessary (I don't advise this), but I wouldn't push it further than that. The purpose of the radiator is to cool the water that flows through the engine, keeping the engine from over heating. If your radiator blew and all of your fluid is out of the system, it can no longer keep the engine cool. Once it overheats, you risk blowing the head gasket, warping the head or completely ruining the engine altogether. With no fluid to keep it cool, this can happen very fast.

Hope this helps!

Lucky you... we all dream of that day!

Why fix a gift of that ... you've got angels!

Suggestion:
1. Change oil every 3 months
2. If you really want to fix it... check the line, load with graphite as per manual.

Best

i have this exact problem did u find out whats wrong?

And I am sure the car is gutless. There is little that you can do with it if it has died. You might be able to find another one at a scrap dealer and it is not too difficult to do the change over. The cost of a new one will bring tears to your eyes but the 2c engine is bulletproof and will give you thousands of miles of hassle free travelling. The older turbo engines need to be idled for a couple of minutes after a run to let the turbo wind down. If you don't they will run without oil and suffer premature failure.

WHAT INFORMATION DO YOU NEED.

any parts place should have it do you have autozone,pepboys,napa,advance auto just to name a few should have ur parts or they will tell you where to get them

Try 877-800-2727

did you do a maintenance routine check? like air filter and fuel filter...lastly, do an engine compression

Blue smoke in the exhaust usually means oil is leaking into the compression cylinder and is burning with the air/fuel mixture. This would definitely cause hard starting.
As for how it's getting in there, that depends on how the car has been maintained. How many miles are on it.
First thing you should do is check your oil level. Make sure it's full. Keep track of your oil consumption for at least a week. Knowing how much you are using up can give you an indication how it's getting in there.

This could mean worn rings and cylinder walls or bad valve seals. It could also mean a crack in the block. This might shed some light on the cold air problem as well. Especially if your car overheated recently. Regardless what the cause is this is not a week end job. If your not comfortable with the thought of engine parts laying around find a good mechanic.
I really hope this helps and good luck.

you need to find out what the output of the tps should be at normal operating temperature (tps = Throttle position sensor). Most are three wire sensors, one wire is a supply rail usually 12volts or 5volts, the next wire is the output of the sensor back to the vehicle's control unit and the third wire is the reference earth which should always read as zero volts or just above zero ( like 0.2 volt) you need to locate the output wire, the voltage on this wire will change with throttle position so when the throttle is closed ( at idle) this wire will give you a voltage. You loosen the fixing bolts on the sensor and move it very slightly to change this reading to whatever the correct reading should be. On most vehicles here in australia, the tps is set to .9 volts but you need the correct voltage for your vehicle. If you find that the sensor has insufficient adjustment to give the correct reading, replace the sensor. If you find that the supply voltage is incorrect, refer to a wiring diagram to confirm where this wire receives its power from. Trace the wire and check the voltage until you locate the issue. If this wire is fed 5 volts from the vehicle computer, check the voltage AT THE COMPUTER and if it is still low, high or missing, replace the computer. If the voltage is correct at the computer, trace back to the sensor checking the voltage until you locate the issue and repair it. If the vehicle has a Delco Remy computer, have it tested and repaired by a qualified technician ( some delco remy computers had an issue with cheap Japanese electrolytic capacitors) DON'T ATTEMPT this yourself, these computers use multi layer boards and MUST be repaired using special equipment or you will cause catastrophic damage. Contact your local dealership or garage for the correct sensor voltage when the sensor is in the idle position or purchase the manual for the vehicle which should contain these and other voltages along with workshop procedures for locating issues within the engine management. Having a manual is always a good investment and you can sell the manual if you ever sell the vehicle..
