Ok, here goes...

First, it started simply enough....rewired the front speakers in my car, no biggie. Went to work today, cruising around 110 km/h, no problems..car running fine, then the much dreaded SES light comes on. Of course, I have NO idea what it could mean, so I pull over, check things out....engine rnning fine, temp was good, oil pressure good, all of those things....so off I go the rest of the way to work. 5 minutes back into the ride, the light goes off...ok, so that's GOOD....but of course it once again comes back on another 10 minutes or so. I get to work, check things out again, and I have NO clue what to look for anyways, but I couldn't figure out anything wrong. Same deal with the ride home...a good ride, smooth...an SES...then it went off...back on for a ways..then off. I intend to check for codes in the morning, but right now I'm paranoid as heII...any way that I messed with a wire or something while I was rewiring the dash speakers..? If not, what could it be...? Everything runs fine, sounds good...I'm HOPING for something simple....

 

Go to the FAQ on the homepage (www.thirdgen.org) and find out how to check your engine codes (it's easy and requires a paperclip). Then tell us what the code is.

 

I know how to read the codes, I'm just waiting for daylight. I was just seeing if anyone had similar experiences they could relate.

 

Mine has aways seemdto be my EGR it randomley likes to set the SES light

 

EGR.
David.
I left Ben message.
I'll keep phoning evey day until Pomona & them.... .....

 

EGR I bet.
Mine did that untill I took it on a long fast highway trip...

 

Could be a mass air flow sensor. I get an intermittent code 34 on my 86

 

Ok, so it threw me a code 32:
Fault in barometric pressure sensor circuit OR
Fault in exhaust gas recirculation valve diagnostic switch OR
Fault in electronic vacuum regulator valve

How do I interpret this, is their a chance of anything else being at fault? I guess this DOES mean EGR, right? or any other thoughts on the subject...? I'm checking into the EGR today. Thanks so far, all!

 

Code 32? Check the vacuum connection around the EGR valve and solenoid. The one at the solenoid that goes into the electrical connection (Back of passenger side engine compartment) has about a 1/4" piece of rubber vaccum line. Chances are its dry-rotted out

 

Upon checking the hoses, I may have found my problem. THere's a 'thing' located behind/slightly under the plenum (see image - it's in the area circled, but under the plenum, in front of the coil), I'm not sure of it's name, with two hoses running out from it's left side...it looks like there should also be a hose attatched to the top of this 'thing', but it instead looks like a bike tire valve when you remove the cap. Where would a hose for this lead to...? I'm stumped.

 

That's your fuel block. The two hoses that go into it are your fuel lines. The valve stem looking thing is your schrader valve. This would be where a fuel pressure gauge is hooked up to. Usdually there is a cap that screws on top of it but no vacuum line there

 

You are so lucky
Remove the EGR (100mm) chip out carbon build up, lube the shaft with a few drops of oil, work the shaft to "lube"
Test to see if holds vacuum
Replace using gasket goop on old gasket.
NOW fix all vacuum leaks in hoses.
Get going
You'll be pleased.
This is labor but great rewards
Honest.
Get going!

 

I agree with MDV6man, check out the plastic vac lines of the EGR system. One runs from the EGR valve to the EGR solenoid. One runs from the EGR solenoid to the EGR vacuum diagnostic switch. One feeds the EGR solenoid with vacuum.

If the EGR vac diag switch sees "no vacuum" due to a crack in the vac line, you'll get an error code.
