Howls w/ warm driving turn off key sart again runs good 20

Do you have any codes in the ECM ? Have you checked for any vacuum leaks ? Can you add more detail information as to when it first began to have issues and what have you done to correct this problem.

You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.

A howling noise from a diff is an indication of the gear mesh( pinion to crown wheel) is not correct. Several reasons being worn pinion bearings--loss of preload on the pinion bearings --- crown wheel carrier bearings failing ---not sufficient preload on the bearings---wear on the teeth from incorrect diff oil in use. or simply wrong diff oil. The grade should be 80w90 OEP for normal or special oil for limited slip diffs.

there is problem with relay PGMFI is under left leg.

Don't rule out fuel pump. Had a 95 do the same, ran great when cool in morning then when it got hot in afternoon, it would quit. Wait 15-20 minutes & go again, sometimes got me home, other times a few more miles until it cooled down again. Luckily I had access to a fuel pressure gauge. Cool in morning had 49 psi, when it quit, 2 psi. Wait 20 minutes, 49 psi again. If you can drive it around until it starts to act up then run into a repair shop for fuel pressure test it will confirm it. If not, they may need it all day to monitor the fuel pressure & confirm it is pump. If your a gambler, change it & fuel filter. One thing I did get was trouble codes indicating a lean mixture, due to starving for fuel. Have you cycled your key to retrieve any codes yet?

Hey.......my 2003 Vue did the same thing. The rear wheel drive was bad. Had it disconnected and now I have front wheel drive. No more howling
