A friend of mine also has a 1jz and his has an idling problem. On start up it will idle consistantly at 1000-1500rpm. It will do that for about 3mins. Then I guess once it starts to warm up, it starts bogging down to below 500 and then back up to 1200. Almost like its fighting to stay on. If it does ever decide to even out, it will stay around 1500rpms.
We have tried to swap out the TPS. After that didnt change anything, we figured that it wouldnt make a difference anyways 'cause its just a sensor. We swapped map sensors. No difference. We've beeeeen looking for vacuum leaks. Cant find any. Ummm... I think thats it. Im stumped. Dont know what else to do.
He said that maybe its the fuel filter. So I guess thats the next task. Can you guys think of anything else that might be causing this prob. Thanx in advance.
O... and he swears by Supraforums. I tell Supramania is WAY BETTER! Naturally!
