1988 Mazda B2200 from North America - Comments

Engine used to smoke a lot during warm-up.

If your Mazda Truck smokes a lot during warm-up, you might want to read my other article entitled "I like it so far and think it will be a great little truck".

I'm happy to report that it is a great little truck. The only problem I've had is getting it to pass emissions since I rebuilt the engine. The carbon monoxide output is over 6 percent, which is 3 times the limit. Hydrocarbons are also high, but just barely under the limit. The first time I tested it, though, the HCs were over by 10.

However, at that time I didn't replace the camshaft at the same time that I rebuilt the engine and I haven't had the emissions retest since I finally replaced it. Perhaps now it will pass the emissions test. I did rebuild the carburetor and it had no signs of being excessively worn or dirty or gummed up. In fact, the carburetor's interior was virtually spotless except for the floor of the float bowl, which is typical.

The new camshaft made a world of difference in the running quality of the engine. When my neighbor recently went to Home Depot with me and I started the truck as we were leaving the store, he asked me if it was running at all, which it was. If you stand 20 feet away, you can barely hear it running.

I'm getting about 20 mpg with normal daily driving which for me involves about ½ in-town and ½ highway driving. A recent trip across PA (Route 30) produced 26 mpg. It has plenty of power and I drove up the Tuscarora Mountains in PA with 800 lbs. of equipment in the bed, and that trip was driven with the old camshaft still in the engine. I'd like to see how it would do with the new cam.

I'm curious as to the mileage that other owners of the carbureted 2.2L engine are getting. Also, I'd like to know if others had similar emissions failures and what was the cause. Please email me at webmaster@cowpensvets.org.

I am also getting around 20 MPG. I just bought the truck this year and the guy who sold it to me told me where to go to get the emissions done. I don't see how it could have passed emissions considering the Cat was hollowed out, and some of the vacuum lines were blocked or left hangin. The timing was also off in the dust. Naturally I found all this out during an inspection I did after I bought the flippin thing.

After replacing all the vacuum lines and doing the exhaust from the cat back, the truck runs great, except for a rough idle when its cold.

Excellent idle, fair pickup, and quiet that you think it stalled when your siting at a light.

I have a 1987 B2000 with a 2.0 engine. I cannot find an emissions routing lable for the truck, nor do any of the shop manuals have the routing for this year. My local dealer have been likewise unhelpful. "Bring it in at $125 per hour and we will have a look at it." My word, I only want to look at the emission hose routing of your shop manuals. Can any one please help me? My truck started running rough lately. I had "too much help" when I recently replaced some of the emission hoses. It was a "best guess" to put the hoses back in the correct port.

Thanx,

Doug.
