Hey fellas! I bought an OBDII reader and cleared my codes...CEL came on again after I replaced plugs and wires..

0305
0300
0133
I have a source at ALLDATAdiy.com now to get my codes after I pull them from the ECU..

I used 7mm silicone plug wires paid about 50.00 after market brand and BOSCH single platinum plugs...Misfire on Cylinder #5 was showing up before and after I changed plugs and wires..I ordered a coil set from Utah and hopefully I can get this job done right..I am assuming that the misfire is from the coils... almost positive ...correct me if I need to check something else..Can I do the coils without pulling the intake? It looks too tight..I ordered the following just in case..
The used MAF works fine though so one problem down..I also ordered the valve cover gaskets and 8 bolts and also the upper intake gasket..CAN OBDII seems to work fine..$115.00 online..I have three imports Mercedes,Volvo and this Rover..It will get used often..
Thanks in advance for help and replies..

 

Based on you 133 code, you have bank 1 sensor 1 slow to respond so you should at least replace both front 02's.

 

Thanks Dmike! Which bank is one and which bank is two? Sorry for asking but I could not find it inRave..

 

Bank 1 is left side, bank 2 is right side.
