this doesnt really bother me bc my car rarely sees low rpms, but i was just wondering why my car bucks when i go below 2000 rpms? i cant really describe the bucking its just odd.

 

bad tps ..bad ground..could be a number of things

 

Because that's how manual transmission cars with low torque work... they don't like driving in low-gear with low throttle.

 

manual transmision cars arnt supose to buck (unless u cant drive). and a 13b dosent really have low torque.

 

My engine did it because of an out of adjustment TPS. Easy fix if you have a multimeter.

 

did you check those, I'm really interested in the solution.

 

Did nobody else catch this failure of a statement?

 

ONLY CAUSE YOU POINTED IT OUT!!!! ^_^ Nice Catch

 

check it out maf... me have same trouble, only disconnect and cover well ............

to separate from heat of the hose of the radiator, Cover with ALUMINIUM PAPER....


:ok:

 

Agreed

 

John Deere offered a rotary engine in farm tractors back in the 60's or 70's I believe. It was an option for a grand total of a year or two, because they simply did not have the torque to take a hit and keep themselves running.

The 13B is no different, these are not torque monster cars.

 

my car doesnt buck at all.. even when its 1500rpm in 5th

 

That's cause it really only does it badly in first...

 

It could be a vacuum leak. Under higher airflow a leak will typically make less of a noticeable difference.

 

I have that problem at exactly 2200 rpms, and it's only noticeable in first and second gear. My TPS has a giant dead zone on it so that's obviously the cause of it for me atleast. There's a really simple schematic in the faq section for building a calibration circuit for the tps using two leds and like a resistor.

 

TPS adjustment is absolutely the most sensitive and critical adjustment above any other. Usually within 1/2 turn of the adjustment screw, that's how close the tolerance is.

 

remember its not good to have the car below 2000 rpms...so try to stay away from this...
