Do you have any fault codes stored in the ecu memory.
i dont know if there is as i just bought it in march of this year . i havent done anything with the ecu since i got it.....
it has ran perfectly since this . it struggled again on me this evening this time in 2nd gear with the engine managment light flashing on and off....... i might take out the cat tomorrow and see if thats gone causing this fault?? when i bought the jeep the engine oil level was a bit over the full mark on the dipstick so maybe that has damaged the cat over time?????????
The first thing you should do is have the fault memory checked to see what fault codes are stored. I would not remove the catalyst just yet.
i found fault codes ..... P0216.....P1614......P1612 & P1613 that were stored in the ecu memory... do you know what these codes are???
