Rb20det Flat Spots While Accelerating

[thepunisher]

Hi, A little hard to explain but my 32 has what i guess you would call flat spots when accelerating sometimes. For example you will be accelerating smoothly then the engine basically stops for a second then runs smooth again. Sort of like this lol, baaaaaaaaaaaaaaaa.........baaaaaaa.....baaaaaaaaa. What could it be, fuel pump or something? has anyone else experienced this problem? cheers

well im guessing you have put a few mods on there and that is what i think is causing the flat spots.

Have u re gapped your plugs to .8mm?

Checked your coilpacks for cracks?

check your AFM is performing properly.

(By the way do you have a full exhaust???)

i have the same prob, i think a tune would fix it...

The only mods are 3in cat back exhaust, pod filter. Havent had it for long but i do intend to modify it. ill prolly get it tuned once i do a couple of things to it. Thanks

could be the injector/s?

possible probs

fuel pump

coil packs

spark plugs

start with these, and go from there, a dyno run will tell you if its leaning out (fuel related) under accel or if its spark related (misfires on dyno)

Turns out the afm plug was just loose (idiot ). Probebly should secure the pod filter as well.
