The pinging noise starts when I accelerate to 25 miles per hour and goes away after I hit 35 why is that and how do I fix
This noise is detonation. It is an uncontrolled untimed ignition from hot spots in the combustion chamber igniting an incorrect air/fuel mixture. IT is harmful if left un repaired as it has the capability of melting holes in pistons.. Run the fault codes or check /change the air/ fuel mixture settings and ignition timing of the engine . Most engines run around 10-12 degrees advanced and any more than that will help cause the problem, as the spark occurs too early and the extra pressure built up by the combustion will combust the rest of the mixture in the cylinder. Fuel quality is important so if you are using a standard grade fuel( 89-91 octane rated) fill with a premium fuel with a higher fuel octane rating . Give a miss to E- fuel mixtures
Is it an electronic pinging? that description can indicate different problems. I would assume since its on acceleration that its coming from the engine. I would try a tank of premium gas with 93 octane, or try a different brand of gas. If all else fails get a good tune up.
SOURCE: Changing from mile per hour to km per hour
okay,for one,the odometer doesnt read in miles per hr,it reads miles driven, and two i have no idea if its possible to change the odometer to km traveled,if you're talking about the speedometer,its already there,get a european cluster :p
SOURCE: Won't go past 40 miles per hour
no not muffler problem could be bad gas or TPS sensor how many miles you have on it?
SOURCE: Won't accelerate past 40 miles per hour
these jeeps did have a small problem with the tp sensor. i would also have the back pressure of the exhaust checked to see if you have a catalytic converter choked up.
SOURCE: 2002 ford Ranger 3.0 v6 (auto) rear end noise when accelerating on curves.
Grab the bed of the truck and vigorously rock the vehicle from side to side. If you hear clunking in the axle, you probably need to check the carrier bearings in the differential. I had the carrier bearings, wheel bearings, and seals replaced in my mother-in-law's 1991 Ranger for $280, and it rides like a new truck. Well, ok, it rides like an 18 year old truck with a new rear end. I provided the wheel bearings and seals to the shop, and they provided the carrier bearing, lube, and labor. While the axles are out, check the surface where the axles ride on the bearings. If they are worn, there are undersized bearing available, but it is usually cheaper and easier to just by new axles.
SOURCE: There is a loud noise at 45mph.
Find a quiet empty stretch of road. Go 50 mph, put the trans in NEUTRAL and shut the engine. If noise is still there, swing car left and right to detect noise differences. Could be hub or axle bearings. Not engine or trans if noise is still there. Hope this helps
