i have a 2003 str with about 160kms. i had it in 2 replace my egr valve & a few studs on the exhaust manifold. i was kind of rushing my mechanic because i really wanted the car back 2 go out for new years but when i went to pick up the car it was running really rough, shaking everytime i stopped. when i accelerate it feels fine only when i come to a stop it get really rough & i knew it couldnt b good driving like that but my mechanic told me it was fine to drive so stupidly i took it anyway. new years day i brought the car back to him to try n fix it & i dont know what happend but he ended up bringing it back to a jaguar dealership & they replaced all 8 coils & a o2 sensor control chip in bank 1. from driving it on new years i needed burned out my catalytic converters so i had it brought 2 a shop to put performance cats on & its still running the exact same way as it was $5000 ago.
heres all the codes its still giving & a little video clip so you can hear how bad it sounds...my cars just been sitting in the shop for the last 2 months & they cant figure out the problem. im really hoping someone here can.
P0301 P0302 P0303 P0304 P0305 P0306 P0307 P0308 - i know these are misfires on all cylinder but i just had all new coils
P1316 P1646 P0400 & P1000 12 codes in total

i forgot to mention i dont know to much about cars to begin with, im sure its pretty obvious lol but when i first took the car in for work the only problems i had was a ticking/chugging on cold starts & it was supposed to be from the EGR & a leaking driver side exhaust manifold. now i got 10 more problems & i feel like putting a brick on the gas pedle & driving the car right through his shop lmao jks

From what you say, the mechanic made a mess of the EGR/etc job. I don't understand why you've paid $5000, as he should have fixed his bad work at his cost. You now have so many problems you'll need a good tech to figure out what the real problems are and which codes, if any, are knock-on effects. Unless you're good with cars you're not going to DIY this and I doubt we can guess what has been screwed up. The last thing to do is any non-standard parts until it's fixed IMO.

thanks for the reply jagv8...around $3500 came outta my pocket so far & probably close to $2000 my mechanic has paid for the coils & some towards the new cats. i know i shouldnt have to pay any extra costs for problems that he made while doing the other work but hes a friend & did help me out plenty times in the past so i can just leave it all up to him now lol
the last i heard from my mechanic is he thinks it might be a leaking/cracked breather hose...can just a leaking air hose make it run that bad ??? im hope its something small like that but with my luck i doubt it will be something cheap like a hose lol ....thanks again

Have the coils and spark plugs been connected in the right order? It'll run with some of them transposed but like a three legged donkey down a spiral staircase. It won't do your emissions any good let alone valves etc.
