sputtering x1

[WindWalker]

Guy's I have an 2000 X1 Lightning and it has a new coil pack with wires , injectors professionally cleaned and it still bogs down and misses under hard acceleration . I'm lost as to what to do next. It idles fine and runs the same way hot or cold.

Did you check fuel pressure? Intake seals?

 

[WindWalker]

Yes sir I put a new fuel pump on it and checked all intake seals.

TPS reset?

 

[WindWalker]

No I haven't done a TPS reset yet. I do not have the ecmspy or the cable yet.

 

[rchuff]

Ecmspy and cable are a good investment. You next step is what pur pony said ( TPS reset.)

 

[WindWalker]

Well guys I found a loose 02 sensor today and it's running a lot better, but still needs the TPS reset I think.

I think I'm in the same boat. Mine has been bogging under load and will correct if I shut the throttle and then reapply. Does anyone know where to find instructions for a TPS reset specific to the X1?
