Idle Problems after installing ACT Streetlite flywheel

[Statix393]

i got a 1995 GSX and i just installed a new clutch and ACT street light flywheel

and i am having major idle issues..

most of the time when i coast in neutral my rpms dip and sometimes i stall.

or even when i let off the gas and just start slowing down and reach around 1000 rpms it just dips. sometimes it catches and sometimes it stalls.

ALSO

My check engine light came on

AND

i have a air/fuel gauge thats not wideband but it says im running really lean which worries me...

i have been told not to trust it because its crappy one but i donoe.

At idle it doesnt have any reading

but at WOT it says its VERY LEAN!

any ideas?

do you have a stock ecu,? Def dont trust the narrowband there pretty much useless.

 

[Statix393]

yeah stock ECU nothing is modded..

 

[2GFWDbeast]

well definitely ditch the narrow band cause it useless ever more if your n/a. Since you have a lighten flywheel the stock ecu cant compensate with such a drastic rpm drop, and cant compensate fuel so the car dies every time when thrown into neutral.

nah im not n/a that was my old eclipse i got a new one now.

but is there any fix to this other than chip/piggy back?

and would this cause my engine light to come on ?

Wait so your car is turbo then? Well i would check for boost leaks. Also your idle switch might not be working, seeing that it tells the ecu when to idle.

You're not venting your blow off valve are you?

I'd suggest checking what that CEL is for and then work from there.

i have no idea what this guy did.... i jsut got the car and fixed the clutch and flywheel.. now moving on to engine.. i took it to a place.. oxygen sensor and manifold pressure sensor is dead...

the guy said this guy did improper work on like everything... so i gotta start basically from scratch.. and see if i can redo everything
