XU7JP4 Hard to start and wont rev - Grant - 26-03-2012
As in title really, the new fire ring on the exhaust is on, and now it is a bitch to start and will not rev over 2.8-3k rpm. I thought it was ecu settings to begin with so left battery off for 45 mins but this made no difference...
I'm thinking blocked cat?
Any ideas anyone?

sounds like something is blocked in there, is it hard to rev it up to that rpm?

Yeah, can't just slam the TB open, have to sneak it up to revs...

Knocked the lambda sensor wiring or anything?

i take it it doesnt limiter bounce at 3k? when was the last time you had the exhaust renewed?

RAC have just left. Wouldn't normally call them but the car was nowhere near home....
Turned out to be a blocked cat. Going for a new one to Longlife tomorrow :heart-attack:
Would replace it myself, but the old cat is welded to centre section and I don't have a welder... Unless someone wants to earn some dollar? Lol
Thanks for the input guys!

Why don't you just take it off and crack out the jack handle and a sledge hammer, and smash it all out.
