sputters at 2k rpm's

[stevestevesteve]

Alright after driving for awhile something foes wrong with my car. if i keep it around 2000 rpm's it will drop and rise around 200 rpms. it will be fine is i give it gas to around 2500 or let off the pedal and drift around 1400. but when i keep it steady at around 2000 rpms it will like to sputter and its not my cluter since i can hear the engine. and i can feel the car jerk slightly. anyone got any ideas? i have new msd wires, and ngk bpr6es.

oh and another problem is my idle on a warm start is around 75-150 rpms.... way to low. car is completely stock, and i have no tuing devices.

Any advice or ideas?

maybe a sensor? what may cause the low idle? anyone?

Does the car stall? Does it put out any smoke? Does the car drive? Is the Check Engine Light on? Can you make a video so we can diagnose the problem?

sure i will take my camera with next time i take a drive.

car doesnt stall
No smoke
it drivers fine, just concerned about what was stated
no cel

Hmmm... well then I would do the following:

Change Spark Plugs and maybe throw on some NGK wires
Clean Throttle body, especially the throttle plate
Test the IAC
Then maybe, if you HAVE TO... play with the BISS screw

That's all the solutions I have for the minor problems you are experiencing. But a Video of inside the car and of under the hood might help us pin-point.

to my knowledge msd 8.5mm wires are the best, which are insatlled already. i will go make a few stop tomarrow and i will get a video of a warm start around noon tomarrow.

ah ha! found an old video before i replaced the plugs and wires. found out one of the old spark plugs was dropped before installation so gapping was off but i have the new ngks in there now

Check your Timing dude. Probably off a teeth or two. There's no timing belt CEL for that I bet your car is quicker now, I'm betting your timing is advanced.

Also, check your voltage on your alternator and have your battery tested at the nearest auto parts store. That could affect idle and the flickering of lights as well.

have you disconnected the battery recently? you may have reset the ecu and now it's trying to adjust the idle...happens to me all the time.
