87 RX Turbo loss of power
Posted 23 March 2004 - 09:03 PM
OK, so now its running and the coolant leaks are gone but its basically running very very poorly. I adjusted the TPS according to haynes/chiltons specifications but the thing wont idle and the lag is horrible. I have readjusted and fixed that. But the lack of power still exists.........it now idles fine but if I give it full throttle it just bogs out to zero power. If I nurse the gas pedal I can get a little bit of power up to about 4000 RPM but any higher RPM's and the power is just gone. I have seen the turbo kick in a few times but its almost impossible to get enough exhaust going to activate the turbo.
I checked the firing order.....all is well. I double checked the fuel lines and evap lines.....all is well. All the electrical from the wiring harness is hooked up.
Please note that this is not just a performance issue.........it barely runs and I dont think I could get it past 40 MPH on the street.

just keep the RPMs low and it's not too loud.

Its code #23 and from my manual seems to indicate an Airflow Meter issue. Now I am trying to test the Mass Airflow Meter but the chiltons/haynes manuals are not very informative.
The MAF connector is firmly attached.

Also.. make sure the contacts are nice and clean.. soobs are real sensetive to having dirty contacts on their sensors.

The only problem left is that it is running slightly rough until the turbo kicks in. I figure there is some carbon fouling that will burn off in due time.
YAHOO!!! My RX is back to being street worthy.
Thanks for all your help.
