Whos Good at Reading Datamaster
Whos Good at Reading Datamaster
Well I put my car back together new motor/tranny and this thing is stutter and poping outta the exhaust.
I have a small cam with a pcmforless tune and it idels fine and revs fine till you put a load on it. I made a datamaster of me driving around to see what you all think. Seems like its leaning out at WOT according to my wideband. Looks like the right 02 sensor is dead as well. I don't know how to read sensors to well so Let me know what looks funny. I unplugged the 02 sensors and drove the car and it ran good. That points to that 02 being bad right? Also I need to know how to check a map and MAF sensor because they are tripping my SES. I need to know what the ESC failure is as well. I am going to order new 02 sensors and try to test all the other sensors. Also my car will not shift into OD with the car like this??
Here is the file its the only hosting I could find

Generally not a good idea to put multiple posts on different forums, particularly when you already have responses to the original thread.

I'll try and take a look at it tomorrow.

Man, that is one messed up log.
1. The ESC code you are asking about refers to the knock sensor circuit. Something is wrong (ie bad knock sensor, bad harness plug, bad wire, etc.). Here is a reference to help you figure this out: http://shbox.com/1/4th_gen_tech2.html#knock_sensor
Since you are getting that code, the pcm is defaulting to the max values in the knock tables. You are getting tons of timing retard because of this.
2. Your tps voltage is a tad low at 0% throttle.
3. The right bank is adding a ton of fuel.
4. At WOT, your car is still pulling vacuum (out of normal specs).
5. Your timing all over looks horrible. Especially at WOT. I can't remember though if it shows the spark advance after the knock retard is taken out or not, but it's still not right.
6. Your O2 is not dead. If it were dead, it would hover around 452 mV at all times.
7. You have a MAF system failure (DTC 48).
The right bank is adding fuel because the O2 is seeing a lean condition, for one reason or another. Are all your plug wires on correctly? Do you have any exhaust leaks before that O2 sensor? You definitely have some bugs to work out. We'll try to help as much as possible. Injuneer might notice a few more things as well; I just took a quick glance.

I responded to your earlier post on the "Computer....." forum..... I suggest you read it. You are running a good chance of damaging the engine.
