Hi everyone, again id like to thank fellow member for your replies in advance. I just been having a minor issue with my S13, its a 91 coupe with the KA24DE I noticed on the way home today that the check engine light illuminated for some reason, then i noticed that the car idles kinda high (900rpm), but worse parts is if my car is moving it wants to stall, when i kick it into neutral while i am rolling (idle drops almost to 0 and i rev her to bring it back up, then it stablizes after a few tries). It does the same thing if i rev her high and fast, mostly makes the idle bounce a little after approaching norm idle speed (drops to 3-500rpm then goes back to 9-950rpm).
Its the worse when im am going highways speeds and i throw her outta 4th gear into neutral (IE a freeway exit), she stalls. I jiggled a few connectors thinking it came loose (it happens alot on my Z32), but no go.
So far in the last week i had it i replaced the spark plugs, fuel filter, installed a air intake, new o2 sensors, flushed radiator, and put in redline water wetter and prestone coolant mix, added redline fuel system cleaner in tank, and changed oil with mobil1 and bosch filter. She ran alot better after all that. BTW She ran fine with all the mods and stuff i had above, she started to do that just today for soem reason. Sorry for the long post.
