ok my car a 1987 rx7 n/a its been acting up ,when its cold it doesn't do the problem but when its at temp., it does the problem ,the problem is at 6000rpm does not give no more at wot, but when i ease off of it a little it goes pass little 6krpm but the problem still exist even when i do that.

i put new temp sensor today ,fuel pump and filters, and plugs like 2 months ago.

i have no emissions ,6pi wired open,no cats ,headers etc..

 

grounding issue?

 

i check them and they look fine to me

 

what is the symtoms of the bacv going bad? and also the map sensor?

 

map sensors would make it run bad all the time also not running at all sometimes..

 

how bad would it run like ? and would it cause the problem that i have?

 

does anyone has an idea?
