2 weeks ago y replace my rotary engine because i let the original engine just go bad without doing notihng to it.Now i regret every minute that i drive my car because now when i start my car and while its cold it runs fine but once it gets to normal running temp. starts to missfire and would not go more than 3200 rpm. Does anybudy have any idea what can be messing my car please contac me at willworkhard2@yahoo.com thank you

 

Was the newer engine any good?

 

check your tps, check your thermowax, check for vaccum leaks.
