Any thing else that I should be doing? This truck has to pass. Its the only vehicle I have.

 

cats? EGR issue?

sorry i cant be of more help...we dont have smog testing here

 

Just before it was parked 2 years ago
changed plugs
cat conv
new alternator
new started

it had passed a presmog at that time

looking at the paper it looks like the EGR was looked at but it was decided the issue was the cat

 

'87 doesn't have a Check Engine light. It has the spot but the factory didn't use it.

 

Now that is interesting! thank you!

 

Mine's an '87 too. I wired the light to work on mine.

 

I am trying to find something on this so I can print it out to take to the referee when I am ready to go. Any idea where I can find a statement from ford on this or just prove that I can show them?

 

There should be a database on that sort of thing, I mean there has to be more than one 87 F150 on the road in you're state.

 

Ok reading on the EGR valve, should I just troubleshoot it or just plan on cleaning it .
How often do they go bad?
Should I just buy one?

 

The high HC at idle is tune up items. Pull the EGR and soak it in PB to clean. Bet it will pass with the other. Items you bought.
