SR20det bad idle and breaking up

[90rhds13]

I was driving my 240 with a blcktop sr swap today. I decided to slide my car and ended up red lining it. Now my car has a crappy idle and it breaks up bad after 3000 rpm's. Also bake fires if i try and rev it in neutral.

I checked the compression and its at 150 in cylnder 1,2,4 and 145 in 3. So i know thats good i also thought i might have broken a rocker but when i tok my valve cover off they are all fine aswell. I do hear a ticking noise comming from the intake side.

Can some one please help me asap. :bash:

Id check to make sure all the shims are still on top of the retainers

i am new to nissans where are they and what do they look like? I also forgot to say that now my afr is at 10 on my aem gauge.

[Sileighty_85]

they sit under the rocker arms they are little round "spacers"

And also check IC pipes and vac lines for leaks

Sounds to me like boost leak.

A BIG one.

I bet a coupler is barely hanging on, if at all.

Boost leak!

ill check for a boost leak today. Also going to see if i throw any ecu codes

[90rhds13]

No boost leak. When I go to turn it on and I don't hear my fuel pump at all. Then to start it now I have to give it gas. I never had to do that before. When it finally starts it runs super rich. My afr reading on my aem wide band is 10. I can also hear my intake sucking in alot of air. Don't think I ever noticed that before.

Try unplugging the injectors one at a time see what happens. Maybe one is stuck or leaking.

hahahaha its wierd i thought the same thing and it maker no differance not even pulling the coil packs did something. I am so stumpded.

[Csomme]

MAF? check it out bro.

[90rhds13]

maf has no change also. this thing isdriving me crazy

[90rhds13]

i just tried unplugging the injectors and then the coil packs. There was a dif in idle.I followed the steps tp read the ecu cel codes and my led just stays lit and never blinks.

thank you everyone for the help. I found out the problem. When i did my rhd conversion the old blower motor out side air vent wasnt sealed all the way. It had a pin hole where water dripped in the car and water dripped onto my the plug for the ecu. I removed the ecu and resealed the hole. Dried the ecu and the plug. Everything works fine now.
