Hi guys. Some of you might remember my rough running post. Well, that's taken care off. A couple vacuum lines were bad and the air cleaners heat valve was stuck pointed to the radiator. Do I need that for emissions?
Anyway, two big things. The EGR doesn't open. The manual said the solenoid is supposed to allow vacuum to it if I unplug the solenoid, and it doesn't open the valve at all. I can pull the pintle with my hand and engine will roughen, So i assume the EGR's fine. Computer or the solenoid itself? It has vacuum to it.
The oil pressure gauge is almost always pegged WAY past 80. I looked for a broken wire and I did find one that was chafed, and I fixed that but no difference. It's worked for about 20 miles out of the 1000 I've put on since I've had it. When I unplug it, it stays pegged. When it is working, and the engines off, it doesn't read zero. It reads a touch under 10 then goes up to 30ish with a hot idle. What's up with this?
I really wouldn't mind just letting the EGR be, but we have emissions testing here in Massachusetts. Plus I dunno if it's pinging from not having it functional, since I have no clue what a ping sounds like.
