An oil drip maybe 1 qt in a month and it only leaks when car is at idle never when driving or car is off Thanks also want to know if there is a quick fix for gas gage and remove stuck spark plugs


Clean the engine well and look for source of leak, one place is oil pressure sending unit. try Marvel Mystery Oil in fuel tank to help free sticking fuel gauge sending unit. Stuck spark plug is bad if in aluminum head. Spray PB Blaster around plug several times after engine is warm and let sit. I have had cross threaded and corroded plugs take out the threads in the head have had to insert helicoil to repair it. Try removing the plugs when the engine is hot, aluminum expands when hot.

My 1997 Jeep grand cherokee is running real rough when I accelerate. Now while driving it it keeps stopping but will start right back up? help???


check the cables of the spark plugs, some times it occurs that the cables get loose from its plastic retainers and touch any metal in the engine, causing missfire of the related spark plug, hence rough running of the engine. Put all cables on the retainers making sure none touches the bare metal of the engine. That should help.

Rough idling,seems to have power loss,and takes more oil than usual


is there smoke coming out of the exhaust? if so what color? if it has white smoke is usually a blown head gasket. if it is a bluish gray it is oil. check your radiator when it is cool. if it appears to have oil in it it could be a blown head gasket. if you leave the radiator cap off start the motor, if you rev the engine and coolant shoots out of the radiator (compression from the cylinder forcing water out) it is a blown head gasket. this can cause the motor to run weak and idle rough and oil to disappear.
if you happen to have a compression gauge take out all of the spark plugs look at the spark plugs if they all look the same or is there ones that look black and sooty(running rich) or looks green(burning antifreeze/water) white Burning hot) http://www.dansmc.com/spark_plugs/spark_plugs_catalog.html
check the compression of each cylinder it is easier if you have an assistant for this. place the gauge over the spark plug hole crank the motor once or twice. the gauge should be around 120 psi (pounds per square inch). if all of the cylinders are under 120 psi more than likely you have worn or broken rings which will cause low compression causing it to run weak and consume oil.

Car starts and runs fine then after 30 min or so runs rough


Check the primary and secondary resistance on your coil and resistance and gap on your spark plugs. Sounds like you have a high temp foul out.

MY 1997 SATURN STARTS UP FINE BUT IT WON'T GO FASTER THEN 15MPH IT'S HESSITANT IT FEELS LIKE IT'S RUNNING OUT OF GAS THE CHECK ENGINE LIGHT IS NOT ON IT DIED ON ME 1 TIME BUT STARTED RIGHT BACK UP IT'S...


You will need to do a fuel pump pressure check. You will need to borrow a gauge or purchase one ($40 to $50), attach it to the fuel injector rail test port, it will have a little black cap on it, turn the key to the run position. Your fuel pressure should be in the range of 45 to 55 lbs.

The knocking noise is a little peculiar, check the engine oil for proper level and smell the dip stick. It may smell like gas, if it does, change the oil immediately. The gasoline has diluted the oil and is to thin, causing the knock.
Let me know.
