The engine runs fine, revs and lowers rpms with no problem. The check engine light is constantly on. I use it for a while and when i reach my destination and begin lowering my speed, no problem until that point. When i put it in neutral then the rpms sore up to 3,500 and i have to turn the engine off for a while. After it cools down for 30 minutes or so, back to normal operation. And it does this every single time i run it for a while. What could it be? hat's causing this problem? Please give me light. Thanks.

when checking the transmission fluid always check it while vehicle is running, if you overfill the transmission YOU WILL BURN IT UP. secoundly the high RPM is most likley a cause by a bad TPS Throttle Posiction Sensor. and yes the high RPM can cause transmission damage if you do not fix the problem pretty quick .in this case good idea to do soits getting harder and harder to get parts for these cars TPS-25.00 to 45.00 if you fix it your self, simple to do
you could have a vacum leak some where in the system that can cause high rpm,also if you have a bad tps(throttle position sensor) it can cause this type of problem.you don`t say if you have check to see what is turning on the check engine light and what code is in the computer.this should have been done and may have help to find the problem in the begining.
I looked at info for 1500--5.7L engine. 6 psi @ 1000 rpms 18 psi@2000 rpms 24 psi @ 4000 rpms
Sometimes, you can use analog gage in place of oil pressure sending unit and double check oil pressure that way. If oil pressure is actually low, if high mileage engine, I doubt replacing oil pump will help. I just wanted to add, check oil pressure engine warmed up.
At 4000 rpm what does your speedo say. Your computer may be limiting both your mph and your rpms. I have a 2004 Ford Ranger at 90 mph the engine sputters and seems to miss. It will stay at 90. In neutral it revs fine. My problem is because of chip programming in the computer. Your problem may be the same.
You most likely have an air leak in the intake tract. Check and make sure your vacuum hose or hoses are attached also check for air leaking into the intake behind the carbs. When the bike is running, spray carb cleaner between the rubber boot and the engine. If engine changes rpm you found your leak.
there is a tps located on the intake where the inlet tube for air intake connects, it would be on the left side of the throttle body. does the trk run rough on idle? up/down sputter sometimes stall? Is check engine light on? if no light,check all vacuum lines for cracks/splits loose fit. do this by spraying carb choke cleaner on connections motor rpms will change if leak is present. also spray around perimeter of intake housing where mates with lower intake if engine revs you have bad intake gasket.I Just replaced upper and lower intake on my 98 and shazaam, runs like it should. but do your checks first,unessasary fixes are costly and **** you off.
Yes, the PCM for your vehicle's engine has a rev/speed limit seeting programmed into it. Most stock, non high performance/police package vehicles usually won't go above a top speed of 97MPH. if you were to rev your engine while it was in park or neutral, once the engine reaches the cut out rpm limit preset in the PCM, it will cause the engine to cut back, then it will rev up until it hits the preset limit, then cut back, and it keep repeating that pattern. It may sound as though you have a high rev ignition failure that sounds like waaa, waaa, waaa, waaa, but that indicates the PCM is doing its job.
