My 72 350sl still has a problem with it's idle.
the 72 is running just fine now. starts right up cold or warm a little sluggish but can make 90 on the freeway with no problem. still has 4 of the old plugs.
what it does is after it has sat so a cold or cool start it starts right up but...then something strange. it's idle is about 700 rpm then it raises to 2000 then back down then up then down. it's like someone or something is pushing on the throttle but we're not.
i've released the after market cruise control. so what ever is creating this condition is from the motor itself. i'm wondering if the electronic injection is creating the condition.
any suggestions would be appreciated.
