Clean the throttle body with throttle body cleaner and make sure the air filter is not dirty or plugged.Also clean the mas air flow sensor with mass air flow sensor cleaner.Give this a try and let me know if it took care of your problems.Hope this helps.Good luck.

Car idles fine, but sputters, bogs and dies if gas pedal is pressed.


new spark plugs this decade. (a tune up?0
the filter is part of all 60k tuneups. letting it clog wrecks good pumps.
my wild guess, its lack of fuel flow, do to old filter.
or low fuel pressure.
car is identical to a Corolla. so is not unique or rare as some Geo cars are.
the cam belt not changes, invites valve kissing piston tops. BOOM
end of engine. (costs more to fix then worth of car)
the word is bogging, my engine bogs
if if bogs WOT (wide open throttle) and dont catch up < ITS NOT THE TPS. ever.
tps bad causes short bogs, called hesitations.
The map sensor , is what measure air flow and the ECU matches fuel to this air flow.
my guess, is it does that, but fuel pressure is like 15PSI, bad.

2006 chevy 2500 express cargo van .What is a good oil pressure for this van. it has 150,000 miles runs great


60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

P0102 Code on 98 Chevy 2500 van


Check to see if the pink wire on the mass air flow connector has voltage with key on.It come's from fuse #15 inthe under hood power box.Also called eng 1 fuse.If voltage is present try the old trick of using carb cleaner to see if you have a vacuum leak.that will also cause a high idle oon fuel injected veh.If you can't find anything ther your going to need to see your mechanic to trace the trouble tree down for that code.There is a long process for that code. Good luck.
