Hesitation after 1-2 shift - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

This usually happens when applying say 40-70% throttle.  I shift from 1st to 2nd and for about half a second nothing happens.  This also causes a fairly harsh 1-2 shift b/c the revs aren't where they should be when I release the clutch.  How can I fix this?

i dont know... learn to drive?
release the clutch slower and dont pound on your gas buddy!

Oh, ok.  I must have just recently forgotten how.  :rolleyes:

I don't know about your car, but most cars I've driven accelerate as soon as you hit the gas.  And what do you mean don't pound on my gas?

I'm starting to get the feeling that this is the quality of comments we can expect from this board... driftrx ;p

My '91 manual has never had this problem, so I don't think its your driving style.  Either fuel or spark.  Since it is hard to check these while driving down the road making a 1-2 shift, I'd say its time to either buy a scan tool or take it to a shop to have the ECU codes read.  Probably a throttle position sensor or something like that.  I think www.240sx.org lists a way to read error codes without a scan tool.

So you shift.... depress the clutch and are on the throttle and THEN it hesitates?

Yes, just for like half a second.
It doesn't do it WOT and isn't noticeable when I'm barely accelerating.  But when I'm kinda on it and shifting around 4000-4500, it does something like this...
rrrrrRRRRRR :shift: mmmmrrrrRRRRRRRR :shift: rrrrrrrrRRRR....etc.
