1971 340 Thermoquad Fast Idle Solenoid Applicability - 05/11/13 02:26 PM
Did all 71 340 thermoquads have a fast idle solenoid? My car is a 71 340 challenger rt with auto trans.

Yes they did. The same part# was used for all 71 TQ applications #DR111429 (actually called an "Idle Stop Solenoid").
They are very hard to find (new or used) as the same number was also used for 1970 & 1971 426 Hemis, 1970 340 Six Pack, and 1970 440 Six pack applications. There are accurate APPEARING reproductions but they lack the number stamped into the can and the internals being poorly made, usually don't function well.

Thanks Scott
Do you know if the wire harness is tied in with the main engine harness or separate?
Thanks
