83' 300D is it a fuel problem? Oil problem also?

My 300D starts and runs, then after a while the car slows to less than 5mph and continues to run at that speed. Then out of no where it takes off full speed ahead. Runs for a while and repeats the process again and again. Is this a fuel delivery problem? It has been run on a blend a few times this passed summer.

I also have an oil leak that coming from some where by the air filter. If I put 5qts in drive less than 40miles and the oil shoots out every where its a mess?

Any ideas?

wow, I would get the oil leak under control and go from there, new fuel filters aren't that expensive, and they plug up pretty easily from VO, so start with a good fuel filter and see how it goes.

mike,

There are 3 filters, well the one in the tank is actually more of a strainer. The intermittant problem suggests to me that is the fuel strainer in the tank.

Take off the rubber fuel line where it connects to the steel line and observe how much fuel runs out. Steady full flow stream, the strainer is OK. Slow flow or dripping, the strainer is plugged.

If strainer isn't plugged, take off the in-line filter. Try to blow thru it in the forward direction. If fuel squirts out easily, filter is OK. If hard to blow thru, replace the in-line filter.

If the in-line flter is OK, replace the canister filter. Only test of this is how the engine runs.

Your problem could also be an air leak in the fuel system. Check for any leaks in the fuel line or the primer pump.

the inline filter is only 2.00 at advance auto, and they carry the clear one, which makes visual inspection of the fuel simple, also the spin on filter is there, but they don't carry anything but purolator, so if you want to go back with original, you are going to have to go to an import dealer, or order online, like here... anyway, NAPA stocks the Wix built gold line of spin on filters, around 10.00. your choice.
I never think of the fuel strainer, so it is a good idea to check it's flow, do it with a low tank, and a good jumpsuit. it's gonna be messy.
