1986 N/A fc with 86k miles. has new exhaust, and will not idle when warm. i do not know if it did before the exhaust was put on, because i just bought the car. i would like to get this running right to be my daily driver, please help

 

TPS could be out of adjustment/bad, you may have significant vacuum leaks, or the idle adjust screw (top of TB), variable resistor or throttle stop may have been tampered with.

 

I had a problem recently where my 7 wouldnt stay running I had to feather the throttle when in neutral to keep the car from stalling out. Turned out I had a disconnected tube connected to the intake manifold. all I did was put it right back on and it worked just fine.

 

haven't figured the problem out yet, i adjusted the idle screw and it didn't fix it, there are no vacume lines disconnected, but i looked at the exhaust, and found the Y-pipe is like 1 and1/5 inch! no way is that big enough, could that be the problem?

 

no

 

I have a similar problem.

When my car is warmed up and i start it up "again" it wont start it cracks and stuff for a long time but nothing happens. It cant idle enough i guess?

but when i gas it a few times it starts as i crank the key.

 

If you have followed and checked what RotaryRocket 88 have listed please add these to his chores. Ground and check your BAC. I hope it helps. Worked for me.
