They are the correct injectors, I checked. and I'll check the vacuum lines. the O2 sensor is only about 9 mos old, but I'll check it anyway.


Chris,

It sounds like one of your vacuum hoses didn't get back on, or you have an air leak in something. Is your car equipped with the high impedance injectors orignially? I can't remember which year they started. Is your O2 sensor operational?

My car is riveted on a 750 rpm idle with just an occaisional burble.

I just got a chance to drive it around the block, but it did feel a little smoother and stranger. This could very well be psycho-sematic, but I feel it all as well. I did notice something, and maybe Pat can answer this: This idle is now up around 950 - 1000. I disconnected the neg terminal all during the install, so I'm attributing this to the computer re-learning what the hell is going on, but maybe someone here can shed some light on this. I also replaced some vacuum hoses and cleaned the infamous grounding strap on the back of the engine. I'll post more when I feel more. Thanks,

Chris
