- Sun Sep 18, 2011 10:24 pm #272672 Ok. Well something caused the car to start running pig rich. Did you check to see if any electrical connectors came off under the hood? Specifically, the ECT(coolant temp), throttle position, etc?

I saw you asking about fuel pressures on the other post as well, have you checked it with vac and without vac? What were your readings?

- Sun Sep 18, 2011 11:37 pm #272688 well i was thinking of the sensor on my short ram intake or maybe the one on the exaust but i'm tired of putting money into this an not having any result just in those 2 last day it cost me over 150$ just to change the TPS and the throttle body cuz mine was broked

- Sun Sep 18, 2011 11:42 pm #272689 without the vac i read 48 on my gauge and with the vac its like 41

those are normal. This is an ls motor right? obd1 or 2?

- Mon Sep 19, 2011 2:08 am #272715 its an obd2 motor with the obd1 wire convertion just before the ECU

i have an OBD1 computer with a Obd2 motor

I got that from your previous post. I asked what computer? Should be a P74 or P75 for the OBD1 LS.

- Mon Sep 19, 2011 2:23 am #272723 could it be a PR4

- Mon Sep 19, 2011 2:25 am #272724 yes, keep forgetting that there is an OBD1 version of the PR4.

- Mon Sep 19, 2011 2:29 am #272726 haha it's okay you seem to know much more than i do could all this be cause by my throttle body thats from an SIR and the intake manifold from a b18b? someone told me it could be my ECU that not doing is job well cuz when i put the ECU from an 1.6L civic 98 it works great

- Mon Sep 19, 2011 2:29 am #272727 Try a diff IACV.
