jakefresh Posted June 12, 2013 Report Share Posted June 12, 2013 hello everyone, iv just changed the cat on my 1.4s loop 1999 and it has lost all power! the exhaust is blowing from the join to the mid section, would this cause massive power loss? it feels slower than my 1.0.the weird part is when it gets to about 3.5-4k revs it picks up like normal?any ideas guys? 5 Quote Link to comment Share on other sites More sharing options...

jakefresh Posted June 12, 2013 Author Report Share Posted June 12, 2013 haha, the cat was fitted to the pipe out the box, and there was only one way it could go (one end had a flange for the mani bolts) Quote Link to comment Share on other sites More sharing options...
jakefresh Posted June 12, 2013 Author Report Share Posted June 12, 2013 k just spent 20 mins under the cat theirs about an inch gap between the downpipe/cat section the the mid section? is this the cause? didn't think it would be that bad :/ Quote Link to comment Share on other sites More sharing options...

jakefresh Posted June 18, 2013 Author Report Share Posted June 18, 2013 OK so after getting the exhaust sorted. Still not getting the power I was expecting over my 1.0 after doing a bit of reading I've seen that the throttle body can cause some power loss and a spluttery idle. This is what I'm getting and when I accelerate from lights or a junction it stutters and then decides to go. Its quite unnerving sometimes. Help?!

Ashh Posted June 19, 2013 Report Share Posted June 19, 2013 Clean the throttle body Quote Link to comment Share on other sites More sharing options...
jakefresh Posted June 19, 2013 Author Report Share Posted June 19, 2013 When you say clean do you mean take it off Or leave attached? Using carb cleaner? Quote Link to comment Share on other sites More sharing options...
Pete91 Posted June 19, 2013 Report Share Posted June 19, 2013 Leave it attached and yeah use carb cleaner. I just used a toothbrush and gave it a scrub then got someone to rev the engine a couple times to open it up so I could spray some cleaner in.

jakefresh Posted June 25, 2013 Author Report Share Posted June 25, 2013 right! cleaned the throttle body and checked for air leaks in the process! success! it was sorted. now its idleing very rough, and sometimes just splutters randomly, after a read im thinking its the temp sensor? would you agree?

Ashh Posted July 1, 2013 Report Share Posted July 1, 2013 Before you spend £120 on coil packs, change temp sensor. £30 from TPS. Quote Link to comment Share on other sites More sharing options...
