As most of you know I've been playing round with my car for quite some time trying to get it perfect before I start driving it and something struck me as wierd. I've always noticed my car rev ok but not especially quick then the other day for some reason I turn my car on and damn was it responsive. I mean I hit the gas peddle and the tack flys almost to redline (very nice!) I drove it just to see what it felt like and man was it responcive. I was even pealing out! But then I cut it off and then a bit later cut it on and it was back to same old slower rev. I still hit full boost and all just not responsive and crisp throttle responce as that one time (clearly a big differance). Would this be caused by bad grounds or by throttle plates??? Is there anything else that could cause this??? THanks!

 

check to see that your 2ndary throttle plates are opening up fully, i noticed that mine were sticking a little bit. had the same prob as yours.

 

hum......ok

 

well I'm guessing I have the tb mod. I've always thought the guy before me did the mod but wasn't sure. So I don't think its this because the mod is done and I don't have secondary plates. Here are pics.

any other ideas what it could be??? This weekend is dedicated to regrounding everything. so maybe that but if anyone has had this same problem please let me know.

 

anyone?

 

They're going to seem just a bit more sluggish when hot, because of the "heat sink" affect on the intake manifolds after running her, she can't help but gulp in hot air at this point, whereas when she's "cold", she'll be a bit more "lively"...

You may also want to check out your sensor inputs to the ECU (per the FSM) when she's warm, to see if any of them are showing "wacky" voltages...
