ecu capacitors

hello everyone. i was looking over ebay and i notivced that there is ecu capacitors for my car ( i drive a 1991 3000gt vr-4, 134k miles ) and i was wandering if this would be any good. i know that ebay sells alot of cheap stuff, but i heard sometimes it doesnt really matter. my question is should i get these capacitors or should i get the real thing.

p.s. i heard the capacitors is what causes my idol to mess up sometimes. every so often my car will idol at around 600 rpms or just turn off, and sometimes it will idol at 2000 rpms, but most times its normal at around 900-1000. any help would be appreciated

heres the link for the capacitors:

Your screwy idle is most likely the cause of a faulty IAC.

iac is idle air control right? im not sure if thats a big problem to fix, if it is expensive, hopefully cheap.

so i guess i dont need the capacitors.

what do the capacitors do? what happens when they go bad?

i've heard that if a smell like fish sticks comes through your vents it can mean that your a capacitor in your ecu could be melting, which would mean very bad news for your ecu and worse news for your wallet (new ecus aren't cheap). im not positive on what preventative maintenance helps to stop this or if its even a good idea to change the capacitors prematurely though.

ill try to research it, or if anyone knows, just let me know. oh and i havent smelled like fish sticks yet, so i guess thats a good thing.

$281.29 for the iac at 20% off factory list price (this is for a mitsubishi part)

Try cleaning the IAC first, sometimes it just gets dirty. It's a common problem. If it's the the ECU, and easy way to check it to open up the ECU and look around the base of the caps. If they have leaked then they will have discolored the PCB around them. Some of them also bloat and burst. You will know if they have leaked by looking at the ECU. If not take a pic and post it up and we can tell you if they've leaked.

yup, some ppl ARE crazy. you know why? b/c they are stupid and/or have too much money. take Nelson Bernardes, for example.

the real question is how much of a markup is the "factory list price" from the price of cost ???

I put 20% but i ment 25% anyways I would get my ass ripped if i say dealer cost.. but the cost is much higher then the after market ones..

the links i listed aren't aftermarket IACs, they are OEM IACs direct from the company that makes them for Mitsubishi.

does anyone have a good link on how to clean an iac?

if your caps havnt been swapped, then yes you should do it before they start to leak. THe caps can be found for $5, and once you pull hte ecu, most mom & pop tv/radio repair places will solder on the new caps for $20ish.

so it doesnt hurt to change the caps prematurely? so basically i just order the caps (from ebay? is this ok?) and just take it to an place to have them solder it on right?

Look at it this way. The caps WILL fail. THe question is when. If you wanna wait and find out, the cost jumps from $25 to $200-1,000. So yes, it's fine to replace them early, and in fact I highly recommend it on any first gen.
