Well, after replacing cap rotor, plugs, wires. it still pops thru the intake under load at low rpms, (sometimes) and for the 1st time the eng light came on!

Got po172
po301

misfire only cyl 1, new plug & changed out wire again still no go.

I did look down the TB for oil, pretty clean, very very little oil or anything.

I'm looking at injector next????

when it's popping in OD if I step on it hard it goes like a bat outta hell...

$72 for an injector, figured I'd post my findings befor I spend $$$ if it's not gonna help!

thanks much!

Tony.
