Breaking up sputtering all rpms Just yesterday my car started to break up under load at nearly every rpm, at first it was somewhat intermittent but as the car warms up it gets worse, Could this be an opti going out? I also have some wires in the harness that are corroded and need replacing a efw on the coil and on some of the injectors, I will be ordering a new engine harness soon.
Basically what I want opinions on is wheter or not this is attributed to the corroded wires or could the opticrap be going bad, the wires have been bad for a wile but the problem just started yesterday, which leads me to think opti.
What do you guys think?

I have the same problem and i think its my cap n rotor cause original optis last a very long time unless you actually throw water in it.. but i've already did plugs, wires, n coil. try changing those first and the n go to cap n rotor then opti.. items are not expensive.. coil was 20$ and plugs n wires cheap and cap n rotor 60 on summit.. but i just havn't done my cap n rotor due to money issues but that should be the problem..
bad wiring/electronics will get worse the longer they're exposed to heat if you have bad wiring going to coil and injectors I'd check that first before throwing an opti at it, because first you know it's already a problem and second it's alot cheaper than an opti

Well I have the original opti from when I rebuilt the motor (it worked perfectly) but I dont want to do the work if it is the wiring harness, the current opti has less than 10k miles on itso I am hoping that is isn't the problem. IDK?
Does anybody know the cheapest place to find a replacement engine harness?

Because I am not sure how bad all the wires are but I am going to check them this weekend, that might be an idea if they arent too bad. thanks Myltwon, but does anyone know the cheapest place for a new harness just in case?
Mine did the same thing 800 miles from home. Wound up being the opti and four bad plugs. I wouldn't recomend not getting a reman like I did 
trying to go the cheep way out in hard times. Now I'm pretty sure that one is fixing to go too with 3000 miles on it. Although my stock opti went 193500 miles.
