So my car started to buck and the idol would drop when driving but not stall. So I did some research and replaced the IACV put a new EGR valve,new cat,new 02 sensor. The car drove better then it would randomly buck a little when driving. So I thought maybe it was the spark plugs, so I put new wires,plugs,and distributor cap and button with gasket! Still no love.. So I figured it was to be the vacuum so I took off the intake manifold off and cleaned it real good and replaced the gaskets which where old and I had too scrap them off, and I also replaced the main relay... Now the car idol crazy and I noticed for some reason it stays in first gear.... I am at wits end with this car I need help!!
