HELLO , i have a 98 dodge durango, with 5.2 lit. 4x4, my speed-o- will read 153 mph on my scanner after it warms up, sometimes it reads O and other times it reads fine, when driveing. will this be a computer problem? i have checked all the components involved- and they check to be fine, even the wireing harness checks out. anyone had /or has the same problem?? i will say this to, it has had a crash in the past, not bad but to the front, the bags where deployed,and on the stearing wheel the cruise control setting switch has been damaged and needs to be changed- only the handle is missing the rest is still intact and not shorted... thanks billygyro.
