Ok well my civic is throwing alot of codes... im wondering if all of them can be due to one problem or should i go about fixing all the problems the error codes show.

4 codes.


#7 Throttle angle
#10 Intake air temperature
#14 Electronic Air Control
#16 Fuel injector

The car idles ok and revs instantly when the light is off but it comes on in 1 min or less and it hesitates to rev and is slow to decel rpms.

well i swaped out the TBI unit and coolant sensor on the IM, it throws no check engine light but it idles at 2700 rpm, when I pull on a connecting rod to a diaphram it goes down to 1200 but not any lower, this is without the throttle cable even attached. I believe I have a vacuum line mixed up, does anyone have a vacuum line diagram for a DPFI?

problem fixed, i messed with the vacuum lines till i got it right. my civic now idles great and revs quicker and decels quicker... no check engine light, plus its running alot more lean. I looked under the hood of my 90 STD for vacuum hose diagram since my 88 Civic didn't have it... I realized they have diffrent intake manifolds and slightly diffrent vacuum passages.
