Hi

Vehicle failed emissions test, when checking we noticed the manifold cat glowing red. We checked for air leaks/fuel pressure and injector pattern all were OK. The tick over is OK and I have spoke to a mechanic at TPS who tells me that this engine doesn't have a timing issue. We replaced the cat and sensor and re-tested passed the emissions test, but the cat is still glowing any help on this will be much appreciated cheers
