The dreaded Code 32, again
I picked up a SES light about 2 weeks ago when running 60-65 on the freeway for about 25-30 minutes and pulled a code 32 when I got home - EGR or ECM. ECM is new, checked all the hoses, vacuum lines and electrical connections. All good. Reset the computer. All seems to be well, or so I thought. Last night, running 60-65 on the freeway another SES and code 32.
The only problem I have been able to find is a slight exhaust leak where the front Y pipe and the cat join.
The main cat is about 1 year old and the pre-cats have been gutted.
So the question is - could the leak be the cause of the 32 or should I just replace the EGR.
Thanks in advance for the help

What's probably happening is that your EGR valve is sticking open or closed due to some carbon build up. You can remove it and inspect and clean it also check the vacume diaphram with a hand pump. The EGR is supposed to opperate at highway speeds.Also I cant rember if a 32 is assoicated with the EGR switch or not. If so that is cheaper than the
valve.

To test the EGR on my '86, I used a vacuum gauge (Mighty Vac $35??). The EGR held vacuum, but the plastic hoses from the EGR's rubber connecting hose needed to be replaced. That plastic hosing is cheap stuff at PEP Boys. Carefully use a heat gun to make your bends. Hope that helps.

There is a diagnostic method to help isolate which of the EGR system components are faulty.

This is a very easy problem to diagnos and replace only the faulty part. Most likely the switch, but if you just follow the directions on his site which are excellent, you will know exactly what is wrong. One thing to be careful of though is that the plastic vacum lines are probably very brittle. Be careful with them and get some extra hose beforehand so you can make repairs if any of them crack.

Replaced the EGR switch on my 87-no more 32. On an 87 the switch it self is cheap and easy to replace-BUT trying to plug it in seemed impossible, it plugs in down and behind the dist.I had to remove the dist. to accomplish this. Never again-I'll just cut, splice and shrink tape the wire.
