Over the last few days my car has been acting up. My check engine light has been on solid NOT flashing. The engine seems to be bogging i.e. when I push the gas the acceleration delays and feels that the ECU is trying to cut out the fuel. Thus far I have done the following:
replaced my plugs
replaced the O2 sensor
Replaced MAP sensor
Reset ECU & cleared codes and seems to drive normally for about 1/2 hour then it all comes back.
Please help this is driving me nuts.


Code P0172 which I belive menas my engine is running too rich.
TPS% 5.0
Engine Rpm 1013
Calc load 62.3%
MAP KPA 63
Coolant 174 F
IAT 159 F
ST FIRM 1 -27.8
LT FIRM 1 -19.0
ST FIRM 3 -100
LT FIRM 3 -100

I realize this is probably better suited for under the hood, but I'm looking for quick help.

 

Is this with or without the E-manage ?

 

Both, even after taking out the EManage, it still does this.

 

I got the engine light to go off (wiped ECU) drove for 10 mins and was still off so I installed the Emanage and ran it, then the light came back on after 1/2 hour. Uninstalled Emanage and engine light stays on. Car does what I said it does in first post.

 

Disconect the battery for 1/2 hr and remove the emanage . Then connect it back and drive it for a few days without the EU . 10min is not long enough for the computer to learn or to throw a code . It takes driving cycles . Just drive it normal , Nothing agressive so it stays in Closed loop to set the fuel trims .

After that plug in your scan tool again and look at the fuel trims . and tell me what you find

 

Thanks, I'll give it a try and let you know what happens.

 

Try the map whack. That seems to fix everything

 

My ce light disappeared after a valve job they were so out of whack.

 

Any luck ?

 

It's been raining here and the S is my weekend car i.e. haven't driven it yet. I'll be sure to let you know what happens.
