Hi Guys, just letting you know i gutted the converter today and welded the pipe back together. I took it for a test drive and low and behold... it feels like a real big block now, what a difference. as soon as i looked inside the converter, the honey combs were rotated 90 degrees so it was completely plugged up. i think this has solved my lack of power issue but i'm gonna plug the code reader in anyway and see if anything comes up.
Thanks for your help everyone once again! Happy trails!
Sean.
