hi. our legendary trooper 4jx1 strikes again.

this time when i exceed 2000 rpm the engine suddenly stalls (i mean leterally shuts it self off) and it would start after a 2 or 3 clicks on the ignition.

what might be the problem again?

ive just replaced the rpcv and a sensor last year.

and also it emits black smoke beyond 2000 rpms, a clud of black smoke.


TIA
