failed mot help

franky · July 01, 2009, 12:29:51 PM

i\'ve always had probs passing my mot every year it fails and today it failed again.

this time on emissions figures i have are
the limit is 3.50% for co i got 5.57%
1200ppm for hc i got 1325
i had a new cat fitted last year when if failed does this mean i need another new 1, know it runs rich would this destroy my cat within a year?

also nearside and offside front anti-roll bar linkage has excessive play in pin/bush the said this was easy to fix and 1 got any walk for for it or pic\'s of how to do it

sorting the linkages out so 1 job done. Has any1 got any ideas on the emissions? does a rich running rx7 destroy the cat?

Is it an import 93 or a UK?

If import, you shouldn\'t be having any CAT test..

BlitzBoy · July 02, 2009, 04:26:24 PM

Yep if its a 93 import then the MOT place should not be doing the CAT test

Kevin · July 02, 2009, 04:30:45 PM

I maybe wrong here, but those limits are for a non cat test arent they?

Kevin · July 02, 2009, 04:34:01 PM

Yeah it is non-cat test. Just as a side note, non cat test limits allowed on FD imports were upto July 1995.

Yes, non cat test is 3.5% CO and 1200 for hc

franky · July 02, 2009, 04:43:56 PM

so they shouldn\'t be testing the emissions then? the tests they did were with those figures any idea how i get the emissons down?

Speedline Imports · July 02, 2009, 04:48:33 PM

Your car still has to be emission tested and they are doing it at the correct values which is for a non cat test.
