Another S13 owner with idle problems... - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I think its in the timing. Not 100% sure on this, I also have a 89' 240 with ka24de and somedays for a couple days or so in a row it will run like complete ass. Idling around 400-800 sometimes it stalls out, sometimes when I give it gas it hesitates. Its done this for as long as I've had the swap.

Do you have an update on this?

mr2gons14 · 12-04-2012, 04:17 AM

check ur plug gap with sputtery boost, idle and accel sputtery check ur injectors for leaks (happened to me), check ur maf especially is u upgraded to z32 remember to have a good chassis ground or ull have issues. Checking your timing cant help rent a timing gun from checkers if u dont have access to one

My idle issues all were related to vacuum hoses. Its best to replace those.

mr2gons14 · 12-04-2012, 09:23 AM

I was under the impression everyone had a boost/ vac gauge is reccomend one and have an extra if anyone is in need

Same problem with my KA. Pulled hard and ran fine normally. I found a tiny vacuum line on the back-left side of the engine that had torn. I replaced the line a few months ago and haven't had a problem since. My onboard diagnostic system never threw a code and I did the usual cleaning and unpluging various sensors, etc.

Bottom line, KA's have tons of vacuum lines and they're all old. There's bound to be a leak somewhere.

Just wanted to update an OLD thread, havent been on the forums for a while. I had done a full replacement on the vacuum lines and still had the problems, for a long time I had no other solutions. My only other conclusion was that I may have a bad harness. So I took the spare harness I had, sodered on new plugs where they were bad, heat wrapped sensitive areas, was a new and better harness ready to swap in. So while removing my old harness I spotted a fuel line that was pinched in a area that would not have been visible to me if I had not removed the harness. Fixed the pinched line and put in the new harness, and the car runs smooth as hell with a perfect 700 idle.

Took forever to figure it out, I reccomend that everyone checks their vacuum and fuel lines since these cars are 20(give or take) years old.

The line running below the fuel filter going down towards the chasis.
