hi just put my 1995 impreza turbo in for mot failed BIG time on emissions the man said 4 times over the legal limit changed spark plugs and was told to put petrol magic in tank which i did but failed on re test does anyone have any ideas please and has anyone tried engine diagnostic tools and what did they think any help appreciated

 

Hase you tried buying the MOT tester a beer?...always helps

If you hit a brick then give me a shout as i have a friendly tester who does not mind the odd emmisions test

 

Prob cats fecked!

 

hmmm, and where would this friendly MOT tester be located vava voom?

my 95 de-catted wrx passed everything but emissions ... 0.6% and 0.46% supposedly should be 0.3% ....i can't really afford to do much about it at the moment, just need to get my MOT and pay my tax!

cheers

You'll be lucky to pass with no cat, just fit a catted centre and all should be well.

 

don't think cat is dun in, but how could i check. its got a straight thru pipe put on, my cat is there cause me lambada sensor is still fitted in it

 

Did you have the car really warmed up when tested? Cats need to be very hot to work properly.

 

Lambda's nothing to do with the cat. Just so happens that it screws into the down pipe before any cats, on a classic.

Is the down pipe stainless? If so it's unlikely to have a cat in it. Not an OE one anyway.

 

thanks for help i have lambada then the straight through exaust do u think the cat could me missing i'm not sure what it should look like only had the car 3 weeks and it's been a nightmare where would cat be please thanx

 

Cats are in the down pipe & centre on WRX, down pipe only on STi.

Probably your best bet is to buy/borrow an OE centre cat. It takes 15 minutes to change at MOT time if the bolts aren't too rusted. If you ask nicely on here someone may lend you one. If you're near Bedford, you can use mine.

Just seen your post count. Sorry Welcome to Scoobynet
