On friday I was cleaning and checking the bulbs on my instrument cluster, when I noticed that my check engine light was burnt out! Replaced it and its been on ever since, checked the codes today and it gave me 9 codes!
116, 114, 113, 171, 172, 173, 181, 327, 332.
I looked them up in the Haynes Repair Manual, but I couldn't make sense of some of them. I'm new to the computer and senors running everything on the engine! What can I do to fix these codes?
Engine is a 302.

Thanks!

Since you have them written down, unhook the battery for a couple of minutes and see if the light stays on. If not run it to see if it comes back on and check the codes again.

Ok I just did that and I got 111 which is system pass. Then 332 means insufficient egr flow detected. Does this mean its plugged some where?

Thanks!

See if the EGR valve opens with vacuum. The engine should run rough or die with the vacuum at idle. If not, the valve is either not working or the tubes are plugged in the exhaust side.

Post the complete definition for each code. You can get them from this caption, or the links in it:



For the EGR, study this caption:

I've posted before about my engine stalling, well I thought I'd try driving around without the vacuum line on the egr valve. Just to see if the valve was staying open at idle and causing the stalls. Well it still wanted to stall on me anyways, does this mean that the IAC motor is to blame?
