Ok, I've been having idling problems forever. When you first start the car, everything seems normal, it goes to around 2000 rpm for fast idle. Then when it swaps to normal mode, my rpms drop to 1000, if I adjust it lower, it will want to stall after about 15 sec. If I leave it at 1000 rpm idle, sometimes after about 30 sec or so, it will jump back up to about 2000 rpm, like it's in fast idle mode or something. Then after about 20 sec, it will drop back to 1000 rpm. Then, after about 30 sec again, it repeats. It, doesn't always do that, but if it doesn't and I rev the engine, it will fall to 1000 rpm, then jump back to about 2000rpm. I've check the tps, and it is .5V and 4.5V, just like it should be. I've checked for vacuum leaks with carb cleaner, none found. I've tried cleaning the eacv, it's not throwing a code, but I thought maybe it was sticking. Nothing from that, and I also tried cleaning the fast idle valve, nothing there either. It does this with both my ecus, so it's not that. It does this with my stock tb, and with my gude tb, so it's not the tb sticking. It does it with both my stock intake manifold, my gude manifold, and my jrsc. I haven't swaped out my cam yet, it's a gude cam, could this be the problem? Timing is dead on. Also, on a probably related note, if I hold the rpms at 3000 or up, it bounces. Not while driving, probably because the load on the engine. Someone please help, I'm sick and tired of dealing with this.
