Replying to: tootoes (Jun 14, 2009 4:35 am) You can verify whether the speedometer is reporting the speed accurately by using the mileposts along a highway. For example, driving at 60 mph, it should take exactly one minute to travel one mile. A significant departure from that indicates the speedometer is inaccurate.   tidester, host SUVs and Smart Shopper

hey tidester i did the mile to mile test i was 8 seconds slow so a friend said i was going about 52 and not 60 he said it sounds like a speed sensore dose that sound right to u Replies to this message: tidester (Jun 14, 2009 1:28 pm) tootoes (Jun 14, 2009 2:44 pm) tidester (Jun 14, 2009 4:09 pm)

Replying to: tootoes (Jun 14, 2009 9:20 am) One mile in 68 seconds works out to almost 53 miles per hour and that does qualify as a significant discrepancy. Mitigating factors are errors in timing and constancy of your speed but I don't think they would be large enough to throw you off by 8 seconds. I agree that the speed sensor is probably faulty. An electronic problem would likely give you highly sporadic readings.   tidester, host SUVs and Smart Shopper Replies to this message: tootoes (Jun 14, 2009 2:44 pm) tidester (Jun 14, 2009 4:09 pm)

Replying to: tootoes (Jun 14, 2009 2:44 pm) I have no idea. Perhaps someone with hands-on experience can jump in and offer some guidance. Anyone?   tidester, host SUVs and Smart Shopper

Replying to: arr828 (May 21, 2009 8:02 pm) Sounds like a clogged Fuel Filter or fuel line, based on what you are describing.   I would replace the fuel filter, and then run a fuel injector cleaning additive (like the one made by BG or Lucas).   Should take care of the problem.   In the future, change your fuel filter on a regular basis. Depending on type of engine, you might be surprised to find out the interval can be as little as 12,000 miles. Fuel filters are relatively inexpensive, and most drivers who can change an air filter can change a fuel filter.   Take care!
