slow throttle repsonse

[mcammarn]

so i dont quite know why i have slow throttle response.
just got done doing a head gasket. and while i did that, i replaced 440inj. whith 560inj.
also changed the stock maf to upgraded lexus maf.
i have a aeromotive fpr, but it is not hooked up yet. if anyone knows what size an fitting i need that would be great.

The one that comes out of the rail I think is a 12mmx1.25 to -6AN. The throttle response check the cable itself may be loose. Check over everything really good vac lines timing ect retrace your steps check your plugs.

A good rule to follow for the future is to do one thing at a time. If you fix something big and upgrade something at the same time you don't know what caused the problem.

I personally think your TPS is out of spec, if you didn't touch it then check your timing. Follow the TSRM to check your timing, don't just put a light to it.

what if it could be cps? i had to take it out once i decked the head. but im pretty sure it was put back in the same spot as before.

Do you know what the CPS controls?

Might have something to do with sensing cam position...
