Yesterday i sprayed some engine cleaner and pressure rinsed it after, ever since my car will idle really low, it wont warm up, it wont rev up more than 3-3.5K when in load, it sounds like it is missing. So i let the car sit for over night ( close to freezing temperature). Today i took the first two plugs and no sign of water so i didnt go deeper, i had plug wires out of the distributor for a few hours. i drove the car for sometime to finally get it to warm up, then i drove the car around for 10 miles i was easy on the car the whole time, 2-3 K RPM. But i tried to drive the car on WOT and the water temp would start falling down with in a few seconds so i let go and let the car come back to normal temp.

I cant seem to understand where the problem is,

Currently i unhooked MAF, IGNITOR, and airfilter is out of the car and im gonna let it sit for today and see if i can get it to run right tomorrow.

Any inputs from anyone?

Oh and once it warms up it wont idle, it will just stall itself as soon as i get off accelerator pedal.

Reset the ECU
Unplug MAF and drive it and see if that does anything.
Check if IACV is clean
Give the system some fuel cleaner.

you do have to be extra cautious when washing a 2jz, i wouldnt assume the other 4 plugs are dry just because the front 2 were. In my experience if you didnt cover up your maf and plugs its likely one or both of those. especially with the not being able to load over 3.5k rpm sounds like a maf issue

For now i have left the MAF out, its not gonna be warm out there for a few days, i did cover up the distributor though. hopefully it will start running right once MAF has dried out, if problem persists i'll go at the plugs. Car has thrown no warning lights out, feel a little confused.

So today i tried to start the car without the MAF, it died with in a few seconds. Then i pluuged MAF and started it and it still idled really bad. So i straight away jumped on the plugs, i took out the last two plugs and they were slightly wet, so i took them out and let them sit, but for some reason i cant get my intake manifold off to get to the two plugs in middle. One bolt i cant get loose cus its way in there, any trick for this? or just a longer socket?

So today i manged to get everything apart, the plug in middle was SOAKING like a Mothafuka!
My intake manifold is all Black, looks really greasy/ dirty. Is that normal or should i spray something in there before i put everything back together? Also is a good idea to change all plug wires since i broke one accidentally.

Thanks!
