Ok here is the deal i have an n/a s4 in my 88 rx7. The motor is suppose to be street ported but i don't know how true that is since i didnt do it since ive had the car. Well I had the car down for paint for a few weeks and now i have a serious idle problem i cant seem to figure out. It revs to 6k on start up then bounces from 1000 to 2000 continuously never stops and the car is hard to drive. The things ive done already: changed the tps, change coolant hoses and checked all my vaccums. New belts, plug wires and spark plugs. Changed BACs. I still can figure it out. Any help would be greatly appreciated because im recking my brain.

 

please anybody have any help ive been searching and searching
