i have had this code for a while now and people have told me to to get new coils but then i read the FAQ and it confused the heck out of me i also have the P0155(1001) and P0400(0302) im lost i just need to know what to buy and replace cuz im not a DIY at all and dont know anything in terms of repairing....

thanks for help and yes i did read the FAQ but its confusing to me..

 

If it's been a while, replace the plugs.

Then test the coils and injectors.
