gswede Posted July 2, 2015 Report Share Posted July 2, 2015 On a side note, I can tell that back in the day - driving the old bricks 240`s and the like. We used to remove the airfilter from the factory box just (reststop before control station) prior to having the MOT/annual smog check. Often times the cars where howering close to acceptable limits, even at bone stock configuration, letting it breathe ever so slightly easier did the trick.

Snabb T5M Posted July 2, 2015 Author Report Share Posted July 2, 2015 All of the other checks during her lifetime have been nonexistant emissions. The emission tech pulled up her history and was shocked at how very little she emits even now with all the performance parts. So some mechanical part has failed recently and I need to figure out the problem. I did a smoke test and no vacuum leaks. Installed a new MAF and the AFRs seem to be a touch better. Only other thing to do is get a new CAT. Link to comment Share on other sites More sharing options...
gswede Posted July 2, 2015 Report Share Posted July 2, 2015 Could it be that your ECT sensor and thermostat needs replacing? You could be running rich due to faulty ECT sensor.. Link to comment Share on other sites More sharing options...
S8ET6 Posted July 2, 2015 Report Share Posted July 2, 2015 Lee, if you have to install a replacement cat then I would suggest the you consider having vbands welded to the cat so that you can swap out the cat with a straight pipe afterward, and easily reinstall the cat when its emissions time again.

Snabb T5M Posted July 6, 2015 Author Report Share Posted July 6, 2015 Well, here's the fuel filter I removed from Red. Who also thinks this might be the original fuel filter. A 121,000 mile old fuel filter. Link to comment Share on other sites More sharing options...
Tommy. Posted July 6, 2015 Report Share Posted July 6, 2015 definitely original. I also like the ECT sensor idea. Although that can also result in a no-start. Link to comment Share on other sites More sharing options...
Snabb T5M Posted July 22, 2015 Author Report Share Posted July 22, 2015 Did a compression test last night and 4 cylinders read 165 and one cylinder read 170, so all good there. Did a carb cleaner spray check around the intake gasket and fuel injectors and no stumble in the idle, so no gasket leaks. My volvo mechanic used his Volvo scanner to monitor the car and found nothing unusual. Except for the new rear O2 sensor readings. Generally the rear O2 sensor is a lil lazier than the front, but the new sensor is reading awfully quick to changes. Would a hi-flow CAT change how the rear O2 sensor reacts?But anyway, car is going back tomorrow for emission testing to see how she is now with all the repairs. Last straw is putting a new CAT on.

Burn-E Posted July 22, 2015 Report Share Posted July 22, 2015 I think you're going to need a new cat and you should follow Darnell's suggestion if you do. But I hope not - here's to passing emissions! Link to comment Share on other sites More sharing options...

But I hope not - here's to passing emissions!Meh, not going to start playing flippity flop with the CAT and a straight pipe just cause I might eek 2 more HP from a straight pipe in place of the CAT. If I want a real horsepower car I merely have to drive the Super Bee. HOWEVER, it would make it easier for future CAT swaps if need be again.Oh, and I've got a new Magnaflow CAT coming just in case tomorrow is a fail.

Snabb T5M Posted July 23, 2015 Author Report Share Posted July 23, 2015 Sniff test failed again today. New Magnaflow CAT was delivered today and going to get installed on Saturday. F**king car!!!!! Link to comment Share on other sites More sharing options...
Snabb T5M Posted July 25, 2015 Author Report Share Posted July 25, 2015 Yep, just got new CAT installed, and the old hi-flow CAT had half its insides missing. Guess I know the definitive reason why she's failing. Link to comment Share on other sites More sharing options...
Snabb T5M Posted August 4, 2015 Author Report Share Posted August 4, 2015 It was the stupid CAT!!! Half the insides were burned away (damn race gas)(yes Darnell, you were right, I was wrong). Car finally passed emissions with the new Magnaflow CAT, minimal emissions now!!! Link to comment Share on other sites More sharing options...
