    I've read where there's a TSB on this problem, number: 99-04. The repair involves modifying the PCV and air intake system. Do you know about this? Could this be the issue?

Yes yes very much possible it can be the issue. The oil in the air intake pipe must be coming from the pcv valve.In this case the valve needs to be replaced.But take note that compatible valve not works for longer period of time.The same problem is repeated in 3-4 months.Its advisable to get the OEM pcv valve from dealer .It will work for longer period.There are also few other things that has to be checked and replaced. also change the pcv valve cover gasket, the vent hose located on the back of valve cover going to intake tube. replace oil soaked air filter.This all has to be checked and replaced. Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

Overreving with no power and excessive gas consumption air filter cleaned map sensor replaced fuel pump and filter


usually caused by busted diaphram in fuel pressure regulator allowing fuel to be drawn thru regulator directly to intake manifold. Pull vacuum line off regulator, plug line with golf tee, start car and watch to see if gas comes out of regulator. If yes, turn off car, replace regulator. The regulator sits near the fuel rail on the top of the engine as shown below. I will paste replacement instructions below from autozone.com in case you need to replace the regulator. Please let me know if you have any questions.

Geez!

U got a bad piston rings! U have to pull down the PiSTON to replace the PiSTON RiNGS, oil is getting in ur combustion!

Or

Check also the valve guide oil seal, hope that is the faulty one! 'Cause replacing PiSTON RiNGS will cost a LOT!


Check on that first, Oil in ur air filter means a BLOW BACK gas from ur combustion is pushing the oil into the air filter!

BLOW BACK is a residual combustion air that should have been burned or gone thru the exhaust, but w/ poor seal of ur piston ring, it goes into ur CRANK CASE and into ur EGR system w/ excess oil!

Hope that explains everything!

Many times when oil appears in your air intake and in the air filter this is usually caused by a plugged pcv valve Positive crankcase ventilation valve it costs anywhere from 3-10 dollars.As far as it not starting my guess is they checked the air filter and left a vacuum hose or airbox open.Some of these vehicle will barely run if an air leak is present at the airbox containing the air filter.Would double check for any vacuum lines that may have been disconnected around the air box and that the box is shut and sealed properly.

    It was running fine until i changed the oil,


    MAY HAVE DISLODGED SOMETHING WHEN YOU CHANGED THE AIR FILTER??? COULD BE WRONG VICOSITY OF OIL, WHAT I MEAN IS IF YOU USED A REALLY THICK OIL SUCH AS 20-50 THEN THAT WILL ALSO CAUSE ISSUE. DID YOU HAVE TO DISCONNECT ANYTHING TO GET AIR FILTER OUT THAT MAYBE YOU DID NOT RECONNECT? YOU MIGHT PULL AIR INTAKE BOX OFF AND CLEAN REALLY WELL. CHECK THE T.B.I UNIT TO MAKE SURE THE INJECTOR WIRES ARE BOTH STILL HOOKED UP AND NOT GROUNDING OUT, GM AND CHRYSLER WERE BAD FOR THIS HAPPENING IN THE LATE 80'S. THE WIRES GO BRITTLE FROM THE FUEL AND SNAP OR CONDUIT FREYS. CLEAN OUT WITH A GOOD AIR INTAKE CLEANER THEN TRY AGAIN. LET ME KNOW THE OUTCOME.
