I have a problem with my 92 SE-R. When I drive the car for more than 10 mins and it gets warmed up real good; it start sputtering and even if you have the accelerator at WOT, it barely makes it over 2k sputtering even then. It even backfired once today during my drive home. But what gets me is it starts doing this gradually over a minute or two's time. first off it hesitates while taking off from a stop sign with very light throttle. Then it does the same if you give WOT. I have played with the tps, so I am stuck with no answers. Thanks for you help in advance.

Check Dist. cap, Spark plug wires, Router button. Leave TPS alone unless you know what you are doing.

i have a multimeter and know how to adjust the tps and timing and such. I have new spark plugs, recently new wires, new coil, but haven't checked the cap. will check it though.

btw, what is the router button?

I think he means rotor button? Isn't it the small thing attached to the distributor? It rotates with the distributor, and hits the contacts inside of the distributor cap, sending spark to each plug wire, right? I know someone can explain it better and/or provide pictures for us. I replaced mine, it didn't really make much of a difference. You can examine it and see if it's in good condition.

MAF- check the harness-tight, good conn., Is it grounded? Almost sounds like you are running in "Limp" mode.

Check the harness of the TPS sensor, wiggle it around a little bit. This happened to me but I was able to see the problem because my SAFC was showing me the throttle voltage wigging out and my percentage would trip around 10% and would skip like such 10% 13% 14% 11% 15% and so on and the car would jerk and hesistate so I wiggled the TPS connector around a lil bit and it fixed the problem.

I don't know if this will work but you can try it. Try unplugging the O2 sensor and then see if it still does it. If that does the trick, you should replace the sensor. Also, try resetting your ecu.

i think darren may have been in a drunken haze when he posted hahaha you gotta stop replying under the influence man

I second this. Sounds exactly like what my car was doing. At first I checked the maf and it was fine. Then one day the car wouldn't rev past 2500. The ECU was in limp mode, when I checked the maf again it was completely dead.

That description,unlike my spelling, was on target.

well i thought i had fixed the problem last night after checking the codes on the ecu. it gave me a code for the crank angle sensor and the mass air flow sensor. well the connector on the mass air flow sensor was on there, but no firmly. so i put it on there firmly and reset the ecu. it drove good for all night in short driving spurt. i drove for about 15-20 last night every couple of hours or so. well this morning on the way to school, it did it within 2 miles of school. I can sometime keep the revs between 3-4k and keep it running ok. so it was fine. when i got to my car after class i pulled the ecu for codes and didn't get any, but i reset it anyways. Well while i was less than 200yds from my house my car started to do the hesitation crap again. i tried to keep it 3-4k but then the car had no power at all and then it car backfired. I have checked the ignition, but I have no clue where the crank angle sensnor is (except somewhere near the distibutor) and what it looks like. Not to mention exactly what is causing this crap. I know that was long and hopefully it made some sense. I am getting frustrated. I never had this much trouble with my 1.6 liter. I love my car when it runs right, but it is rarely doing what is supposed to. Thanks for all ur replies.

The crank angle sensor is internal in the distributer. Which code flashed first the MAF or the Crank Angle?
Both sensors can possibly cause the symptons you are describing, intermittent drivability problems.
Heat saturation on the dist., after it cools its ok till it reaches a certain temp.- Possible cause, but my money is on the MAF- got a extra one to test temporarily.(its cheaper than a Distr. and easier to test)

Just my $.02,

does anyone have a spare mass aif flow sensor they would be willing to sell for cheap? or anyone wanna ship me one free of charge? :D Seriously. If I were to buy one because this one has shit on me. Should I go ahead and upgrade to the stillen one? Its only 238 or so. I had a friend replace one on a max and it was like 188 or so.

Is there anyway to test the mass air flow to see if it is working correctly.

To answer your question, i believe the crank angle sensor code flashed first, but i am not sure.

would a mass air flow sensor off of a 95 Sentra GXE (read: ga16de) work?

IF you have a voltmeter you can check the MAF. pull the plug back first. I can't remember which wire is which but I am sure someone remembers But you have to put the ground probe on the ground wire, and you have two hot wires(B13). One hot is a 12v, the other changes with the amount of air. Blow on the sensor and the reading will go up, if it works. Hope this makes sense:rolleyes:

DUDE!!!!..my car is doing the same exact thing, its bucking like crazy under acceleration, and i pulled a code for the crank angle sensor(the CAS is the only plug on the distributer, you have to replace the whole distributer, they dont sell parts to replace just the sensor), anyway, i bought 2 from the junkyard and neither helped, i regrounded the MAF and Crank sensor, changed plugs and wires, reset timing, and still no luck , i'm on the same boat and have no clue what it is, someone mentioned to try the ignition coil, and like said above the MAF, but if you find out whats wrong let me know and i'll keep you posted, i need to fix my car just as much as you do, good luck

anybody else got any clues to what it may be?
