Any Ideas

 

Plugs/plug wires?

 

i had it happen to me a few times...only under verry light throtle (8kpa vacume) and only noticble in 2-3-and slightley in 4th...if u watch the a/f it goes lean for a split seconfd then boounces back...i think its the gap from when the ecu decides to bring the secondarie injectors online...just my thought

 

i thought the secondaries coming on were a problem that caused the 3k hes...Or is it change udner different throttle positions..
