Vs ute running like a pig

[Dog_of_a_v6]

Got brand new pacemaker extractors and full 2.5inch exhaust with a high flow cat now it runs rough as and there's a very strong fuel smell when it idles it sorta sounds like a 4 cylinder and to me it sort sounds like ots struggling to push the air out the exhaust but I wouldn't have a clue I've changed the spark plugs,leads,coil packs and checked a few fuses I even tried resetting the computer but it still did nothing can anyone help me out

Just so I'm clear here, it was running OK, then you had an exhaust system fitted and it ran like a dog from the get go?

Did Series III get EGR or was VT the first one to get it?

OK. Fuel smell aside, does it idle OK?

Try disconnecting the O2 sensor and see if anything changes.

I wouldn't have a clue mate I think so but idk that much about them really

Fuel smell aside, does it idle OK, or is the rough running only when you tramp the accelerator?

Grimes just said VT was first to get EGR.

VT.

Sorta it vibrates but it doesn't drop below about 700rpm unless I turn the a/c on
