P0301 - OBD-II Trouble Code - RepairPal

when the tank gets low on fuel(under 1/4) or less.. the pump, which uses the gas to keep cool, will get hot and start to cavitate(run at slower speeds and cause a severe fuel pressure surge)..the engine will respond accordingly..most will do this as the system gets older..to avoid it and possible premature pump failure, keep the tank at least 1/4 fll..

Chech the air flow sensor in the intake usually just after the air cleaner box-very carefully clean it.Cheers Denny

I's a bad distributor. Get a Spectrum NGS 60. The cam sensor is going bad. A lot of 99-00 models have this issue.

never, ever replace a knock sensor, it is meaningless and will do nothing to make van run better or worse.

The knock sensor NEVER causes a drivability problem. DO NOT change it. Instead, clean the MAF, Mass Air Flow sesnor that's on the air intake tube near air cleaner. It is coated with varnish. Spray with carb cleaner several times and gently, gently brush the wires. Theya re glass coated. Be careful.

Then disconnect battery for 2 hours and then reconnect and drive for 0 miles for computer to relearn engine contrils.

this is most likely a transmission filter being dirty and it needs to be changed regularly as does the oil in your van. this is inside the transmission and needs to be serviced to complete this job i do not recommend you trying this by your self as you could damage your transmission.

COULD BE LOW ON POWER STEERING FLUID IF IT'S A BUZZ NOISE AND WORSE WHEN YOU TURN WHEEL.
OR, COULD BE IDLER PULLEY FOR BELTS. COMMON CONCERN.

It may be the camshaft sensor in the distributor. Sometimes the optical sesor can be cleaned. Most times, need new distributor or reman from ebay.
do not replace the knock sensor, it is never bad. ANd, it is in the middle of the engine. $1000 repair for nothing.

See this ste too.
