lumpier idle after tune up

Hi all,

So i just did a bit of a tune up.

cleaned up the throttle body and the resonance valve.

did the coils, wires, and plugs

coils and wires were mercedes and i switched to buemi and Karlyn wires

plugs were FR8DC+ and I switched to F8DC4.

there was a slight lumpy idle before and now it's much more pronounced.

any ideas?

oh - and the PO stripped out the cover bolts . . . .

thanks,
dave

i looked around - vacuum looks good.

harness is new and throttle actuator looks good when i cleaned it.

i wire brushed the ground studs on the coil too.

it's actually pretty good now - almost perfect.

need to test vacuum maybe. have to read up on how to do it.

how do you check throttle controller?
