SCOTTY!!!!

I have a 1991 manual Miata and every time I take it out of gear to cruise in neutral or take it out of gear to stop the car, the RPMs drop and the car almost turns off. I have changed the fuel pump, fuel filter, and I tried seafoam but nothing seems to work. please help!

(I love your work by the way)

Forget SeaFoam. SK says it was designed for 2-stroke engines. I like GumOUT and B-12 ChemTOOL. Make sure it contains "PEA."
