We recently purchased a '92 Mazda B2600i 2.6 L 4cyl pickup with 120K miles. It idles great but after driving it for about 10 miles it loses power and you can only go about 40 mph. If you try to accelerate it spits and sputters and backfires. Yet if you pull over and put it in park, it idles fine again. The check engine light never comes on and if you let it cool down it will run fine again for about 10 mi. A friend told us that it might be the computer but we're not sure.
