*Is my timing off?*

[way2slowtalon]

The car runs like junk, and bucks at low rpms. Any ideas from this log?

did you let it warm up...because if ya did it should be way higher than 96. How long did ya let it run??

We need more info in general

here is a better one when it was warmed up. Below 2000rpm I have no power at all, not sure if this can help.

Have you checked for boost leaks or exhaust leaks?

Kinda strange that his o2's don't pick up until he's off the throttle. What do your low, med, and o2 fuel trims look like? Checking for vacum leaks is a good idea like xero said.

 

[1993TalonTsiAWD]

Do you have a after martket boost/vac if so look where your vac is should be 18-20. If not you my have a leak. Also build or buy a boost leak tester. look on vfaq for all the instuctions on how to build and use it. Go from there. If you can get the base timing set it's 5btdc on most cars. After that if your feeling up to it turn the engine clockwise with a braker bar until the lines line up one the two gears, if there even one to two teeth of. Stop driving it and get it fixed or you will have more problems. Also note even if they do line up the other marks on the oil gear and crank pully may not, not common,but does happen. To check those will take more work as in removing the engine mount on the drivers side, then all the belt's and pulleys, then my fav the t-belt cover...have fun with that, after that you can see if there all lined yp. In fact look on vfaq for the complete disassemble and install of the t-belt componets. Don't do more than you have to start with the basic. like I said. timing, also check fuel filter, spark plugs, and wires. This is as much info I can give you based on the datad you have given us. Do you have any codes at all?? still need a bit more info. Also what octane of gas you running??

Derek

 

[way2slowtalon]

91 octane gas, and 0 CEL codes. Here are my trims for that table. Will check for leaks tommorow. (Metric Log, lost English)

From those fuel trims your running a bit rich down low. is your car stock?? tell us more about your car in general

also how long did you drive around for those fuel trims?? beacuse you have to keep a steady pace to get good numbers. There no wot values rather crusing values

the trims for the o2's change all the time as long as the car is in closed loop mode. I didn't want to see the WOT logs becasue that's not where he has the problem, it's down at the bottom end of the powerband.

I didn't even think o2 trims could reach that high. I think you're the victim of a dying 02 sensor. At the connector, on the sensor side, between pins 3 and 4 (the bottom pins with the locking tab facing up), there should be 12 ohms of resistance at room temperature. On the harness side, perform a continuity check between pins 2 and ground and 4 and ground.

I know thats not what I was talking about. I was talking about the fuel trims as in low mid high, not ft02 two different things. But I do agree those are to high, I wasn't looking at those thought just the fuel trims which are no good for wot values that's all I'm saying I think they change like evry 5sec or so. Which to thhe ecu is a long time. But if you look at the low one it's a bit rich. It had 10.7 % more than needed, the closer to 100% the better. actually you can go a bit on the lean side and get better gas milage, but theres a fine line. Anyway were talking about two different values fuel trim and 02 trim which I really don't use much anyways

Do you have a AFPR?? IF not that's part of your problem. You can't run a 255 without one. Your running rich. And I'm going to out on a limb and say that you may have damage your 02 sensor from running that rich.
