Check Engine light and loss of power?
Petraman just called me from the car on his way to work and asked me to post up a problem he just encountered.
He was on the road and the check engine light came on, accompanied by a massive loss of power. He says he had to actually mash the pedal hard to keep the car moving, and keep it in boost just to amintain speed. The trans wasn't slipping, and the RPMs were where they should be for the speed, but it just wouldn't go without lots of accelerator. After a few minutes he says the CE light turned off and the car went back to normal.
He pulled the code with the turn key, and got back a code 43. Unfortuantely his phone died just as he was saying there was another code.
Any ideas?

When posting codes, please take the time (out of courtesy to those who will read this topic) to copy/paste the text of the code description from Techinfo, so we don't have to.
Code 43 could be the crank sensor, cam sensor, ICM, or associated wiring.

I will most likely check this out when I take possession of the car, unless it causes him problems. He told me that this happens every once in a while, and everytime it is code 43. I am betting on crappy grounds, as we never cleaned the one under the ICM on the coil bracket.

Actually, there were no other codes. Yeah, this code has popped up before, but it has never been accompanied by a loss of power like this. I'm mostly posting this for Will, just so he knows what he'* in for
BTW, thanks a bunch for posting this, Brian. I wanted to make sure this got out before everyone went to bed, haha.

My suggestion would be to fix exhaust manifold leaks (only because you know they are there), then check the wiring, clean the grounds and ensure all the connectors are plugged in fully.

I would agree with an intermittent 43.
Your to do list:
1. Remove the ICM. Clean the bottom of it, and the mounting bracket surface. Clean the connector. Reassemble with dielectric grease.
2. Do the same for the Crank and Cam sensors. PULL them and clean the detector face as well as the connector pins.
3. Do the same for the main wiring harness connection where this portion of the circuit branches off, just behind your alternator. This 'branch connector' ties in the branch that consists of the ICM connector, and the Cam and Crank sensors.
