It feels like its hitting a rev limiter at 3k RPM, and it just sputters till then. Now I am throwing 3 codes, 5, 10, 14, map, is because of the vacum routing, but I think I fixed it yesterday so that is no problem to me. But I had this problem on my ZC, and it was the sensor on the back of the intake manifold, driver side, not hooked up with right connector. But on the Y8 htat is not there. Timing is retarded by maybe 2-4 degrees due to the high compression, didnt want any pinging. Can anyone post pictures of there y8 manifold installs on there 88-91 just so I can check it out, or maybe see if I did something wrong?

What I eliminated was vacum and the DSM injectors.

check all vacuum lines make sure they're connected and in the right order. I forgot to plug one of my intake tube lines (connects to the valve cover) and it did the same thing...car wont rev pass 3K.

 

Thats why I wanna see a pic, just to double check all vacum lines and sensors or what not.

 

in codes??? check your injectors, clips for the injectors see if they're loose that maybe your culprit

good luch

 

Checked that already, I even tried stock injectors yesterday, same result.

 

How do you know the difference between an automatic and standard y8 intake manifold? I thought the one I have is a standard.... But I cant get it to run right, and am just wondering if thats the problem...

 

Is the Y8 suppossed to have the Intake air temperature snesor on it? Or not?
