Hello,
My friend has a Saturn sedan 1.9L MPI, Manual Trans. I Think it is a =
1992 it is around there though. We have been having problems with the =
idling speed and when you push in the clutch to shift to another gear =
the rpms don't drop down when the clutch is depressed. The clutch is =
disengaging. It even stays the same if you have it in neutral going =
down the road. But when you rev it at a stop the rpms come right back =
down. When you start to come to a stop (as you are slowing down with =
the clutch in) the RPMs start to drop but stay above 1000rpms until you =
come to a complete stop. He hasn't got very good gas mileage out of it =
either. But one of his problems is that when he bought it, has bigger =
tires on it that should be. At 60 mph it tacks about 3000 in 5th gear, =
which I think is high. The ratio number on the tire is larger. I know =
the bigger the tire the more power it takes to start off. How much =
bigger is bad? It is sluggish when taking off at a stop sign. I have =
cleaned the throttle body out, cleaned the Idle Air Control valve and =
where it seats into. Check for vacuum leaks, TPS and everything seems =
ok. No codes come out of the computer. Just the normal code 12. We =
have tried different grades of gas and fuel injection cleaner. =
Sometimes is seems it gets worse as it warms up. (Closed Loop) We have =
changed the following:
Fuel Filter
Spark Plugs and wires (no dist. has coil packs)
Air Cleaner
Is there anything else I could check? Any Suggestions?
Thanks in advance,
Matt McCain
