You are burning oil, causing the blue smoke. It is mainly cause by worn piston rings. Also will coat your spark plugs with oily residue. Try an oil additive such as "stop smoke" or another such brand to reduce burning your oil and it may recondition your seal sand stop it all together.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Car has new plugs, wires, dist. cap and rotor, also water pump. Sputters badly when you take off, continues to sputter until higher speed is reached. Also surges occassionally when idling. Fuel pressure...


to me it sounds like your just about to put water down your exhaust mate or your rings are binding up. I recon dump your oil and run diesel oil from now on and reset your timing belt before those new spark plugs end up in your lap.

My 1992 Mighty Max, will not start, its getting plenty of fire, but I don't tkink its getting fuel, what could be causing this?


If not getting fuel then the normal areas to check is the fuel filter, fuel pump but first the obvious is to make sure you have fuel in the tank. If this engine has a carburetor, remove the air filter houseing and pour a small amount of gas into it. Try starting it. If it starts and then dies it is a fuel delivery problem. If it wont start even temporily then I'd check things like wires, plugs, timing, etc (stuff to do with delivering a spark).

92 max
I own a 92 max 370 kms runs good but one day just cuts out while doing about 30 km, I pull over i can start it no problem but when I touch the pedal to accelerate the car stalls out.

It got worse to the point of sputtering on the highway , sometimes i could keep it alive by working the pedal but others would slow down and stall out.

I have changed the fuel filter and plugs seemed to make it a bit better but still stalling. I ran it in my driveway for 10 mins on idle then it stalls out

Is this the fuel pump??
