problem???

[pimpinprelude]

iam not shure whats wrong with the lude. when iam starting off in 1st.. it stumbles a little.. almost like its missing.. and if i hold the gas down .. like accelerating really hard.. boom i get the check engine lite.. i have new spark plugs.. the wires are fine.. (from what i can see, thay look faily new). i thought the stumbling could be the fule filter. but its not.. could this be some sort of sensor???

a friend of mine said that the lite is because of my gutted cat... so i need a dummy 02 sencer... how do i make one??

thanks for any help.:)

Is this on your 88 lude? If that's the case then it shouldnt cause that. Try cleaning your O2 sensor with some hot soapy water or carb/brake parts cleaner. I have an O2 simulator build guide, but I'm not sure if it's gonna work on OBD 0 or pre-OBD systems.
