Possible MAF issue

[demonical]

Hi there i have a 1992 k11 Super S 1.3 with some mods :
1.6 black injectors
Almera Airbox
First cat back 2"' exhaust system with single resonator and backbox
Some headwork
and 1.0 pistons
The problem is at light throttle it act's strange sometimes at WOT also it doesn't accelerate right,cleaned the MAF and the idle valve butt still no good when i do the self diagnose shows 55 ( no issue i guess).Tryed to unplug the MAF it goes in emergency mode i guess and reaches 3000 rpm like there is a limiter (launch control ).Lambda sensor is new so is the fuel pump and fuel filter

does it bog down when you pull away (as you let the clutch out) burble a bit then clear after a second or two

Yes exactly what it does it helped a bit with the cleaning butt still it's there

i had the same problem with the SR20 injectors (only worse) i had to drop the fuel pressure @ low throttle with a modified fuelreg (cured it totally)

Will see if i can do anything about that, the strange thing is that this started happening after i removed the waxstat mechanism

throttle body MAF sensor would a good quess.

i had this problem but mine was the lamaber sensor witch you have already changed.

i changed the dizzy, leads, plugs, fuel filter, injector rail!
