Well just a brief history of the car, it's an 01 GTi vr6 that I bought about 5 years ago. When u test drove it and drove it off the lot, I was in awe with how much power it had as it would throw u deep into your seat-even with 5th gear! I was in love.
Shortly after, little by little the car felt slower and seemed like it was starved of air or fuel of just struggling to accelerate. I took it to the dealership and they couldn't find anything wrong(as usual). I thought if was because I became used to the power and was why it felt slower.
This is 5 years later and I am totally convinced something is not right. It just feels like it running on 3 cylinders not 6. Last night on the freeway minding my own biz a dodge neon with a rice exhaust kept intimidating me til I finally decided to show him how bad a GTi can smoke him(mind u I don't normally race people). I finally gave in and floored it from 5th gear and he was keeping up with Ke neck to neck! When I first got the car it would KILL anything with 4 cylinders! What gives??
I haven't vag'ed the car because the dealerships robs u and don't know anyone around me that can but no codes come up when scanned with a reg ODBII scanner. So I've done some research and found a few things it might be such as catalyc convertor clogged or bad, coil pack cracked, bad clutch, dirty bad MAF or spark plugs and wires. I've cleaned my MAF, new clutch last year, changed spark plugs and wires last year and I don't have most of the symptoms of a cracked coil pack such as constant misfires with engine light coming on and off, more frequent misfires in damp/rainy weather, etc. I've also kept up with reg maintenance with fluids, oil and such.
Is there anything that could be wrong but doesn't cause a code? Because i have zero codes. If the cat is bad or clogged, wouldn't it give me a code? Or if anything else was bad for that matter?
Please help me get my GTi back to normal! Thanks alot and sorry for the long post.
P.S. If I wanted to change the cat out but remember reading that unless the dealer or someone proves that it's faulty, it's illegal to change it? That just doesn't seem logical but thought I'd ask. I'm in Cali by the way.
