[DML] Re: Sudden acceleration syndrome?

["therealdmcvegas" <dmcvegas@xxxxxxx>]

That certainly sound like a problem with your air/fuel mixture. And 
while you're right that the work performed wouldn't have affected 
this condition, something else could have.

Have you been working on anything in the engine compartment in the 
time since? It could be a loose hose, or something else causing a 
vacuum leak. That would mess up the A/F mixture, and would cause the 
engine to surge, as the LAMBDA system tried to correct the fuel 
mixture.

there isn't one and never has been). It may stay at the 2600 idle for 
several minutes, up to 60, or it may just go up and then down and 
anything in between. Hard to explain and VERY annoying.
