1998 Nissan Altima -jerks when driving as if not getting fuel and will often stop at intersections and then **** to get going. Also on highway when I press gas it jerks and sometimes speed will not increase as if it is dying.

Possible vacuum leak when idling high at a stop and surging at speed. Does it do it hot or cold ?

That usually happens if you're in too high a gear. If it also seems to accelerate slowly, you may have a fouled plug or other cause of a dead cylinder.

fuel system flush check spark n check chargin systems

you need to replace crank position sesor.about 50.00 and an hours labor(pain in the *** wait till you see where they put this thing!)very common falure on these....should have come with a replacement in the glove box when they sold them new!

the steering wheel gets stiff, because the car died and your power steering pump is stopped. beeing a 1994, you may have a fuel pump issue (nissan had campaign on those), but most likely no longer available to you, because of the age of the car. they purge campaigns out as years go on. you could have an issue with distributor. oil leaks pass the seal and gets inside of the distributor assembly on the signal plate (internal component of distribitor) and messes with the ignition system/spark plugs. you may also have a broken intake gasket. When was the last time you did a tune up?? changed plugs, fuel filter and so on???

Almost sounds like fuel filter. Check with your local auto shop. They should carry the part and show you where it is located on your vehicle. Good luck.

Check your coolant level. If it is low, what you describe will happen. Water pump works faster as rpm's increase, managing to get hot coolant to heater core (highway speeds). At idle, pump is not working fast enough to get the coolant to the heater core.

It sounds like your Mass Air Flow Sensor is faulty. These sensors will normal show fault when cruising at highway speeds causing the vehicle to almost stall or stall. Replace the Mass Air Flow Sensor with a known good one and test drive the vehicle. This will most likely repair your concern.

sounds like your carb is getting to much air some where check your hoses

Check your air filter & fuel filter first, how many miles do you have on it check manufactures suggested timing belt replacement recomendations
