FC problem.

defiantfc3s · 07-08-2004, 07:05 PM

When I start my FC i have to pump it, while it warms up, it will idle fine at 1100 RPM. After it warms up it will start idling lower and lower. Then I rev it up to about 2500 and keep it there for a second, but when I let off the accelerater the RPM's will fall back too about 200 and then eventually quit.

I have checked the fuel pump, fuel lines, and injectors but nothing was wrong with any of them. Anything I might check?

check all vacuum lines, and or adjust you TPS, you also might want to check your compression.

It's a high idle because I adjusted it to be higher, and the stock idle position is 900 RPM.

stock idle speed is 750, u could have a bad compression> But check all your vaccum lines just to be sure.
