86 240 sedan HIGH IDLE and HARD RESTART 200

Hi Star,

I also have an 86 240 that I had a hard time getting past the emissions test here in WI. On the 3rd try we passed.
I'm thinking you may have an intermittent mass air meter failure. If you disconnect it, and see if you get a start if you run into that no start situation that could prove to be the problem. By disconnecting the MA meter you'll cause the engine/computer to go to a default/bypass which will get you started bbut will give bad emissions results if you were to have to go through a test for emissions.

You might also consider using a dwell meter to set the dwell on that year to set the idle. I had to do that too when I was getting my 86 to pass the test.

Sincerely Bill Nelson Hartford, WI

PS I just found/joined the Brick Board yesterday and already I got 2 great responses to a headlight problem I'm having. On my 1990 240 they will not go out on a turn key and light switch turn off. See my entry. Bill N.
