Car Forum / Volvo Cars / July 2007UPDATE: '93 240 failed emmisions test in Ontario
I passed !!! :-) Thanks to James Sweet for suggesting to use the product to clean valves & injectors. OK, now the facts: In first test,HC was at 83 (linit is 66), CO was at 0.40 (limit is 0.37) and NO was at 903 (limit is 505). In today's test I got 66 for HC ( a 20.4% reduction from last test), CO at 0.23 (a 42.5% reduction) and NO at 451 (a 50% reduction). As you can see, my HC is at 66 and the limit is 66!!! So what do you suggest? I'm OK for now, but if HC increases by just one, I'll fail the test in two years. Should I get the technician at the Volvo dealer to manually clean valves & injectors or should I just give it another treatment or two? Btw, I gave it two treatments. First one was for injectors only. The improvement was marginal, ~ 5-10%. But the second treatment was for the valves. injectors, etc. That made a h*ll of a difference. The car drives 100% better. Accelerration is unbelievable. Thanks. Btw, I used the Canadian Tire brand of cleaners. I must have missed your earlier posting... what was the product he suggested? I've been using Seafoam, a little in the gas every so often and sometimes a little squirted into the intake manifold so it hits the valves.... James mentionned using Techron. I simply went to Canadian Tire. Looked at all the various brands of products and then decided to buy the Canadian Tire brand since it was on sale 40% off. I figured that CT is not doing the stuff, another company is doing it for CT. Since there is no way to be sure that another brand is better than CT, I went with CT. The one that did work for me sells around $13 (regular price). It is pink liquid in a transparent plastic bottle. I'll check it out this week end and will post back the name of the one I used. >I must have missed your earlier posting... what was the product he >suggested?

Having some problems with the link. So go to www.canadiantire.ca and enter "ultra fuel system treatment" on front page in the search box and press enter :-) >This is the product I used: > [quoted text clipped - 18 lines] >>>sometimes a little squirted into the intake manifold so it hits the >>>valves.... >I passed !!! :-) > [quoted text clipped - 24 lines] > > Btw, I used the Canadian Tire brand of cleaners. Apparently driving for half an hour or so before the test is useful for lowering HCs. A tidbit gleaned from this forum a few years ago and not mentioned much anymore... Mike >>I passed !!! :-) >> [quoted text clipped - 28 lines] > lowering HCs. A tidbit gleaned from this forum a few years ago and not > mentioned much anymore... Mike How could I forget - an oil change is also supposed to help HCs. After failing the first test, I went on the highway and drove 100 KM at spped between 100KM/h and 140KM/h then went directly to take a second test. All readings were slightly higher than the first test taken a few hours earlier that day. I did change the oil at end of April. Mobil 1. >>>I passed !!! :-) >>> [quoted text clipped - 29 lines] >> mentioned much anymore... Mike >How could I forget - an oil change is also supposed to help HCs. |
