Ok my car for about 2 weeks now has been idleing real crappy, i haven't added any mods or changed anything to it to make it start doing this, i was coming to a red light put the car in neutral and coasted up to the light and the car stalled. tryed to crank it back up it would turn over, start for like a second and then die again and kept doing this. I had to use the gas pedal to keep the rpm's up. I searched every vaccum hose and the hose from the pcv value that has the "t" in it was off, so i plugged it back up and still have the same problem and my IC pipping is fine also, All the hoses are connected. No cracks from what i can tell, I ran some Sea foam through to make sure. Took it to Mitsu and they said it was the trottle body being clogged, so they cleaned it, It will idle now but at a cold start up it idle's at like 550rpm and when it gets warm it jumps up to 950 like normal.

I have trottle body shaft seals on the way i will be changing those. And also will be doing a compression test today. Spark plugs and wires are also fine. And I have 107,500 miles on the car

I need help.

make sure the all your sensors are pluged in all the way. check on the intake manifold and mass.

 

I have, unplugged the MAF sensor and the car ran worst so that should be ok, tps is fine also, and have checked all the other sensors that i can think of,
