Help! while driving my car today it started to hesitate when I tried to accelerate, I have a 1990 n/a with 133K. Now the car will hardly accelerate at all. It seems like it is getting worse. I have to almost floor it to even get it out of 1st. Also, after driving the area around the stick is very warm and it is a little to shift. Can someone help please!

 

Has anything been done to it recently? Could be many things wrong with it. MAS comes to mind. Check all connectors and clean with sand paper and electrical cleaning spray. Look at the major things that could cause this..Air..Fuel ...Spark. Check out

Forgot one thing..happened to me. The 1990 300ZX (early) had bad PTU's mine was replaced just recently. It was not a recall but is out there on a Service bulletin for early 1990 models.
My car would lose power intermittently after it was warmed up and ran rough when idling.
