i have bought civic with already completely convert to engine b16a but now my car got problem when running.. my car always engine dies in low speed but got 2 times the engine stop running in gear 5 with speed above 90km/h..

1 more thing, my car sometimes always jerking in rpm below 2.5k.. any ideas how to solved this..

 

Any CEL's...?

 

TPS.

 

You need to post details about your car.

 

problems related with engines shut off when running already solved... distributor coil already spoil... but the jerking problem still not solve (suspect come from the idling valve but need to follow up with foreman again).. i also ask foreman about TPS sensor but he said TPS is a hard to make a problem.. by the way, thanks to give an idea..

fyi.. my car, make year 1994, already convert to engine B16A big Vtec...
