My 1995 Chevy s10 has a vaccumm pump which plugs into main air intake cover over the throttle plate. There is 4 holes. Two smaller and two larger. One of each is on the left of throttle plate the other two is on the right of throttle plate. I removed the air intake cover and cleaned carbon build up using carburator cleaner. I thought I had the problem solved. While driving the engine stalls. The larger hole only on the right of throttle plate had some grit/pebbles like inside the hole. I cleaned hole and could go a few more miles before stalling again. It looks like this is coming from where tps is. The only place I couldn't clean to well. How do I clean this thoroughly and properly?
have the same problem?
