started car after 2 years and the idle is lumpy (revs to 2k)

[sweetlikechutny]

As stated in the title. The car had been started after 2 years, in that time I did some wiring and routed new hoses along with other work (clutch, fuse box relocation etc).

Started the car today and it immediately started revving to 2k then back down again, continuously. Any ideas what could be the issue?

(also the down pipe was not connected when I started her, just the elbow)

Tps needs to be adjusted.

Put the DP on a well as you dont want to start a fire.

sounds about right, I did remove the tps while i was working on the car and fucked with it

Thanks,

Would it be safe do drive with just the DP for now? I am in the middle of making an exhaust but need to move the car.

The great master Yoda has spoken! Do what he says. You could be getting a bad reading off the o2 sensor having the down pipe off. Any codes?

i'm gonna say, he didnt catch the ears in the throttle body with the tps

You at least need a down pipe to drive the car, unless you like your supra crispy.

...how?

thanks guys, it idles just fine now. But I noticed the brake pedal becomes very soft when I turn the engine on, and the car seems to bog when I press it. Any ideas?

May be a bad master cylinder. Take the vacuum line off and block it with something and see if it makes a difference running wise. If so change the master clinder out and it should be fine.

Bad master wont do that. Bad brake booster will though.

 

[sweetlikechutny]

can a vacuum leak also do this? I cant see how the brake booster could have gone bad, working fine before I put the car away. I did however replace the line running to it.

 

[mkiiichip]

A bad brake booster, is a vacuum leak. Put a vacuum pump on the line to see if it holds. Or unplug the line and cap it, and see if it runs different.

I forgot to put that metal valve thinger in the brake booster line, seems to be working better now.

I am getting a ticking/shake at idle. I think the sound is coming from my exhaust. Is this a misfire? I also have a leak where the cat meats the catback, could this be the issue? I think I only had this problem after I put the catback on.
