The only *possible* issue is with emissions come MoT time - but even then, don't worry, lots of people have taken out their pre-cats and been absolutely fine with the MoT, the main cat is the main part of the emissions side. As long as the engine isn't absolutely stone cold when they test your emissions it will be fine.

06-02-2017, 03:31 AM #93thanks guys, how would I test to see if there are enough gasses coming out the exhaust?
Well the lexus technician came with his mobile daignostic scanner to my house and plugged it in and came up with only code P1320 which is coil number 5 malfunctioning, can 1 coil cause all these problems cause with all the places that have plugged it their diag scanners they are all always coming up with this code?
I was told by garages that 1 coil malfunctioning would cause a misfire but the lexus technician said because it is a 6 cylinder you would not notice 1 coil malfunctioning and he said what normally happens with the coils is when they get hot under load they break down and stop functioning, is this true?

06-02-2017, 08:33 AM #95thanks Gord, I got a mechanic coming in 20 minutes to do that, will update you guys once that is done
well he did that and cleared the codes and then i took it for a drive, I floored it and the light never came on which is what it always does, he then revved it at about 3200 rpm for about 30 seconds and engine light back on, this time the code was P1315 instead of P1320 which means that faulty coil he took out of bank 5 and put in bank 4 is faulty as the code chges referring into what position it is in, think this is the closest i have come to solving the issue, do you think 1 coil can cause all these problems?
I have ordered a brand new coil from jap parts. I need 6 new spark plugs and wanted to know what the best spark plugs to get are, how much and where from?, any advice please
I think it may have been a coil issue all this time and £720 later it takes 15 minutes to find out but i will wait and see once I have replaced it

06-02-2017, 02:51 PM #97Hi guys, mechanic from lexus came round, swapped coil 5 with coil 4, while doing that he noticed the spark plugs were really black and hardly had a tip on them, this is bad i take it?

As for spark plugs, people recommend the iridium ones.
