well i've come to the conclusion that i have a bad fuel pump.. i'ts the last thing i can think of other than a new dissy... i have irregular rpms in the upper and it's an inconsistant restriction t feels like i hit rev limiter early but i stil have about 2,000 rpm's left. now the wierd thing is.. it doesnt happen all of the time.(odd) any one ever had a similar problem or know what do do.. if u need more info.. please let me know and i'll inform you. thnx ht

 

I have seen a plugged catylytic convertor cause this, as well as worn out fuel injectors....
