Nismo280zEd Posted July 1, 2002 Share Posted July 1, 2002 I'm selling my car.. and over the past two weeks it has developed a problem. my car goes strong to 3,500-4k rpm but then has no power and won't rev any higher? but when not in gear reves fine to 6,5. any thoughts? has new TPS sensor, new water temp sensor, new head unit sensor. i'm thinking it might have something to do w/ air to fuel ratio? any ideas guys? i need to have her running mint by friday. thanx Quote Link to comment Share on other sites More sharing options...
Guest Aaron Posted July 2, 2002 Share Posted July 2, 2002 Do the 280Z's have an Air Flow Meter similar to the 280ZX's? If so, that is what I would guess is wrong. I have seen it on several ZX's, but usually they die around the 2000-2800 range. Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted July 2, 2002 Author Share Posted July 2, 2002 Also... i have the MSA "big bore" throttle body... which since i have gotten have had nothing but problems. . almost thinking about putting the stock back on.. but anyways. when the pedal is on the floor in the car... in the engine the butter fly only opens about 3/4 of the way. Could this be causing maybe the TPS switch to not be making full contact on it's points? Let me know what you think guys. Ed Quote Link to comment Share on other sites More sharing options...
Guest 280Tom'z Posted July 2, 2002 Share Posted July 2, 2002 then its your TB the car needs all it can get at 4k and up while haulin asphalt I had to put a new Air Flow meter on my 76' because it had no low end if you really really need the AFM i might have one but i'm pretty sure you have some Throttle bodie probs and its that simple if its not the TB drop me a line for the AFM Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted July 3, 2002 Author Share Posted July 3, 2002 yeah... i was hopping you wouldn't tell me that. OH well another 400 bucks invested i guess. But the car runs mint until it hits about 3,5 or 4, then the timing goes all wrong and if you let your foot off just a little from full... then it goes past 5? does that make any sense?
