hey

i got a 93 liberty wagon (ej22) and my check engine light has been on for a couple of days

i've done a code check and it comes up as
21 - coolant tempreture sensor or circut
and
17 - fuel injector No. 4

that last one has got me a little stumped and worried??

anyone got any ideas

Thanks

Can't offer much help with the coolant sensor, but check the plug on the injector harness, maybe spray it out with some CRC or similar.
