couple of EFI questions.........
well.....I just changed over my 1.6L 8 valve to EFI and there are a couple of things I am pondering over:
1.) Sometimes the airfilter (box,hose,etc.) make a strange thumping noise as it is pulling in air (almost sounds like a tug boat) and it is really noticable when the headlights or heater is on????
2.) The idle at times is a little rougher than desired???? (I just changed spark plug wires, plugs (cap and rotor) all have less than 1000 miles on them and I cleaned out the EGR valve).......what else should I check???
3.) And sometimes (again, more than desired) when I push in the clutch the idle will drop really low (300-500 rpms) and then go up to normal idle speed????
....anyone with an EFI setup have any suggestions or tips for me - TIA
