WooHOO! My first FAQ thumper! Thanks Shep.
Hello Lapatte, Mike De Vito here, car runs fine cold, but seems to miss when warm, sounds like a vacumn leak to me, a squirt bottle filled with water, spray each vacumn line, on the engine, engine running, if there=92s a vacumn leak, engine speed will increase, then simply replace that vacumn line when the car has cooled off.
