thnx

[jimbo74]

which engine is this?

almost sound like you were tuning it, and knocked a hose off, or advanced/retarded the timing accidentally

[JoeShmo65 [OP]]

22r engine and we checked all the hoses and we did retard the timing on purpose but we turned it back to normal after this happened

mine is an 82, 22R,and does the same thing,I thought it was a solenoid,like the fuel cut off solenoid, Id like to know what is doing this also,thanks for any advise

If you also gave a year it would help. They make subtle changes from year to year which might make a difference in helping diagnosing the problem.

its an 84 it was a 22re but the previos owner of the engine made it carbed

the idle solenoid is on the side of the carburetor. it well have 1 or 2 wires running to it.  depending on year and model.

[JoeShmo65 [OP]]

the book calls it a soleniod valve is that it? the only other wires that i find are the ones to the choke and wat does this soleniod do??

[RN37DD]

  yeah if it's on the carb , thats it.     it shuts the fuel off to the idle circuit when you turn the key off .. and in some it shuts down the idle passage a higher rpm also. just something to check.  I'd also check your idle adjustment screw. and check your egr. 

[JoeShmo65 [OP]]

iev checked the screw and ill check the soleniod valve 2morow how do i check the egr?? i no wat it is but how do i check if its working??

[JoeShmo65 [OP]]

ok i think i found my problem i was checking the idle cut off soleniod and it looks like i was getting any power to it at all but the soleniod does work so dt if ur still haven the problem try checking that soleniod that might be it
