Everything appears to be wired up. Just want to be sure these arent part of the reason its not running right.

 

Do you have any CEL's? What kind of problems are you having?

 

No CEL. Idle drops to like 3-500 when I let off the gas then it bounces back up to 2100. Cant get it to kick down no matter what. Sputters like hell if I rev it quick. If I try to drive slow it cuts out and will stall if im going slow enough. I have a feeling I have a leak in the intake manifold since ive cleaned the iacv, fitv, bled the coolant and replaced coolant hoses and vacuum lines.

 

just spray some carb cleaner around the areas you think there maybe a leak. wait to see if the idle changes. its a quick way to find vacuum leaks and worth a try.

 

Definitely a leak. Not sure if its the injector o-rings or the intake manifold gasket. Hoping for the o-rings but probably not gonna be it. Not looking forward to this job....

 

I wouldn't waste too much time with a chopped up harness and that's coming from someone who works at a Honda and has access to the diagrams, it's just too much trouble and you never know if your repair job will last.

You're lucky enough to at least have a 5g prelude rather than an older 4g which is hard to find in a junkyard, just go to one, pull the harness and replace it. I've done it on an Accord where the harness burnt up and it's not hard at all, just gotta remember how its routed.

 

best advice i can give you is invest in a power probe system. that way you can check continuity and can figure out what wire goes to what. It will definatly be the best investment if you plan on doing any wiring work in the future on anything.

 

I second the power probe!
