6 Bolt Swap Fires and Runs But very Choppy/Rough. Check List?

[-TunedDSM-]

The GSX fired up first start!
Its a 97 GSX, 95 Eprom with Link, complete 6 bolt swap, built motor, built head.

It fires up but wont stay idling, you have to gas it and its very choppy.

Im trying to think of everything that i need to go through but any input would be great!

So far,

CAS (checked for 180 degrees off, also played around with position a bit)
Played With Fuel trims and fuel codes in dsmlink

I DO need new plugs, these ones are bpr7es but theyre old. So new plugs tomorow.

Would the 2g TPS sensor cause this? I have not checked OHM's trough the TPS when spacing the throttle off the throttle stop yet.


The car is kind of non responsive to the gas pedal in a way, If you goose the pedal it just kind of flutters a few 100 rpm's.

I have CAS inverted on Link, and my firing order is 3-2 1-4 on the coil pack (2g coil)

Power transistor worked fine before the swap.

Anything else i should/need to look into? I have a video i'll put up of the rough idling/non responsive gas pedal.

It sounds like your timing is off, you say its at 180 out, but it is supposed to be at TDC!

I'm assuming youve read this, but reread the section on setting the timing!

As far as the TPS:

Press the pedal all the way down with the car on the "on" positioin, and check to make sure link is telling you its at 100%. The TPS WILL NOT effect anything though, in fact, you can unplug it completely and it really wont hurt anything.
