Multiple codes

[nathanmontez]

Hi Guys,

I'm new here and having some problems......

I have a 97 Chevy Silverado Ext Cab 2WD 305 V8 Stock

Right now I'm getting 4 seperate error codes.

306 misfire #6

I replaced the distributor, rotor, wires, & plugs

it is not running as rough now but the error code is still coming up???

117 engine coolant temp circ low

going to buy a coolant temp sensor..will see how that works.

507 idle control rpm high

I have no idea??!?!?!

1406 Mfg control Aux Emission

Also no idea???!?!?

I've been researching these problems for the last 4 weeks online so any help is appreciated thanks!

the P1406 is related to the egr pintle position most of the time it's due to carbon build up, try removing it and cleaning it. check for vacuum leaks at all the lines and around the intake and proper operation of the IAC(idle air controller) for the idle problem. the #6 misfire might be a dirty injector. a bad coolant temp sensor will affect millage and driveability so you'll wanna swap that out right away make sure the connectors in good shape too.
good luck
