I'm thinking more related to too low an engine idle, perhaps due to a misfire (which should light the engine light) or a vacuum leak (which would probably not light the light). Your tachometer should show about 700 rpm at warm idle in neutral.
There can be many reasons for low engine idle, including, as witnessx suggests, some electrical issue. I don't think this is transmission related.
so yeah, check for vacuum leaks and test the battery and alternator first off.
It's also possible that cleaning the throttle body and MAF sensors might help.
Even a badly clogged up air filter might cause this.

Have a 2001 infiniti i30 having a problem with it spittin and sputtern when it gets to 40 mph it catches up and runs fine till it gets to 60 mph if i try to excelerate past 60 it starts chuggin and then its like its not doin anything. Starter went out and it sat for about a month replaced starter and spark plugs and belts. Mechanic who replaced starter said its like it doesnt want to shift into that second gear mentioned throttle sensor or possible water in fuel. It seems to chug worse goin uphill.

I have replaced transsmission oil(don't know the oil is good) and brakes with rotor, after that whenever I brake my car, my car stops, but when I put the leg back on gas paddle, it doesn'st start running immediately, I have to push a lot on the gas paddle. I show it to the fire stone guy and he says transmission slips and putting new transsmission oil may help.
My car is infiniti I 30 1997 model.

It MIGHT be the torque converter, but I doubt it. Sounds more like your mass air flow sensor has failed. Does the tach jump around a lot when driving?

Get your spark plugs changed, was having the EXACT same issue and switched them out and fixed it. Easy fix too, not too pricey. good luck!

I have the exact same car and having the same problem i just wouldn't call mine convulsive though. It started cutting out a few days ago (just while driving) Now its even doing it while it sits and idols. The check engine light is on and its got a heavy vibration and misen while in drive,1,2 but purrs like a kitten in park or neutral (can't even hear it running). I got autozone to do a diagnostics check on it and it read that the oxygen sencor had an error but not a malfunction. ? I was told it may be the coil packs or plugs, its not my air filter i know that, it looks brand new. I'll give you any information i receive, hope you'll do the same for me.
Someone, please help, i'm still financing this car, can't afford it to get any worse. I've had it less than a week and don't know much about it, but it was as smooth as could be the first 2 or 3 days i had it

its a common problem with the i30. Its actually the MAF sensor(Mass Air Flow sensor), which is located right after the air filter. It looks like a 8 inch wide cylinder. It can cause your car to [1: make a pinging noise when your at about 2500 rpm. 2: feel sluggish 3: shutting down your car while idling (this is when the sensor is just dirty as hell and read the air intake properly so your car chokes and shuts off cause the ecu tells it to.) This part is only made by infiniti so you should buy a new one, not used! I think you can clean the one you already have using some sort of cleaning spray (i forgot what its called) and it should temporarly fix your problem for super cheap so you know its the MAF sensor giving you problems. This part can cost like 400-600$ depending on where you live but its very easy to change cause its right behind the air filter. It would take a good mechanic about 15-20 minutes max to do it. You may experience this problem before your light even came on and even if a light comes on, it doesn't actually tell you its the MAF sensor. Once you get the MAF sensor replaced try to clean out your air filter box and everthing before that so you don't dirty your new MAF sensor again. I hope this helps.

Okay so my car was over heating and then shuts off, i replaced the cracked radiator and the waterpump. after that that the car turned on fine 4 times. something was clicking so they tightened the tensioner after that my car would not turn on. if i listen closely while the hood is up i can hear some trying to rotate but stops. what can this be, so i have an idea on what needs to b done?
