Most of the times if i switch into a gear fast and slam the gas the car seems to bog a little, and then start picking up ( no, no turbo lag). If I ease on the gas instead it will seem to go faster.

 

supra or a 7?

 

How many miles on your spark plugs? How many miles on your fuel filter.. Ok last tune up?

 

Well , I got the car a few months ago , and the plugs were changed to NGK's right before i got it. Dont know about the fuel filter, might have to check that.

Mad 7tist- rx7!!!

 

Exactly what 88gt told you... Also an air leak in the intake system could also cause such action. I don't know how much similiar a Mass Air flow sensor is to the Map sensor(rx7), but on another car of mine. I had similiar experiences turned out the MAF needed cleaning. And yes, dirty injectors could possibly be a problem as well.

 

Side note:
stock 3rd gen injectors are more likely to leak before they gum up and hinder flow.

 

What about a fuel filter change what are the chances of that?

 

i would look into the tps/dbl throttle controll. does the car make boost and just not go? you are sure the clutch is not slip[ping right? i am assuming that if you down shift it , over 3,000 rpm , it will get boost? but just bog?

 

mad 7tist- the clutch is not slipping for sure.

Car is making good boost . Let me tell you I have midpipe on a stock ecu ( yea yea yea... i know its bad ). Car does have fuel cut so i never go over 5k rpms. Dont think that has anything to do with it...

I am going to check the fuel filter and injectors, thanks.
