i've got this problem that has slowly gotten worse and i'm looking for info on where to look first. it started about 2months ago... 90 NA .. i just have a momentary loss of power and as soon as i let off the gas it stopes .. i think to myself plugs/wires> replaced still no fix..... checked the codes on the ecu>> no codes.... i recently redid the whole intake... the tps is out of whak(broken) but seems to not affect it. to me it seems like ignition break-up but anywhere in the throttle and rpm and gear.... anyone???????

 

I think you might have answered your own question- if your TPS has a dead spot, that could be causing the problems...Other components that could cause similar problems are: fuel filters, water thermo sensor (intermittent open), AFM (dead spot in potentiometer), bad grounds, CAS going out, etc...
