Well ive had my swap done and running good for a while now...Yesterday i decided that i needed to extend the ecu wires finally.. THe car starts up but it dies a few minutes later...Also i try to give it gas in the park position and and it bogs and wont make it past 2k rpms....Did i screw up on the extension of the wiring or could it be something else?

 

Sounds more like a mechanical issue then an electrical one, but it could be one of a million reasons

 

did u use usb cable for the sheilded knock sensor wires?.that was a really bad move ,you have to run over the knock sensor wire from sensor to computer .goodluck

 

rpm signal still good?

 

Yeah THe Rpm signal is still good but the idle is extremely low , LIke 400rpm and after i leave it on for a while the car eventually dies...this is in the park position!! SO use shielded USB all the way to the Knock sensor? I only used the USB for that little portion which i extended? Could that be the problem?

 

sounds like problem i am having
my stock ecu is not as extreme, i can start to drive it, it bogs real bad getting ready to stall, then fixes w/e and is good to drive


the power fc bogs at the same spot, but doesn't fix itself and continues to bog...will not rev past 2700rpms

no dying at idle though

i am currently redoing the fuel. then i plan to check the afrs, and then the timing.
change ur filter, since it's only $10(if you didn't do it during the swap)

 

yes you have to use sheilded wire all the way otherwise it will pick up interferece

 

What do you mean by "extend the ecu wires"?

I had a similar sounding problem when my MAP sensor was not plugged in properly. Have you double-checked all your electrical connections?

 

By extending the ecu wires meaning. I cut every ecu wire one by one and extended it and soldered it. I dont know what could be wrong here.? I look into the Map sensor deal...Any other ideas?

 

Ok the ones i use shielded wire on are the 2 brown wires correct?> So i buy lengthy shielded wire and from the ecu to the Knock sensor?

 

did you fix this problem?

 

bad wiring for the map sensor? but also sounds very mechanical

 

im with you ^^^^ this happened to me on a sr20 swap i did. if it happend after fooling with the wores then thats most likely where your problem is. a grounded/crossed/unpluged map sensor wire will do that. get a volt meter and wire diagram and make sure all the volts are right in the wires, also make sure your grounds are good.
