94 Jeep Grand Cherokee Stalling

by memassey / December 29, 2009 2:40 AM PST

Does anyone know why my 94 jeep grand cherokee will not run at greater than 4000 rpm while in park? It is also not shifting very well and I have to let the engine idle way down to get it to shift. The engine accelerates while pushing down on the peddle, and the engine rpm's increase until it gets to about 3500 or 4000 and then it starts to decrease and it sounds like the engine is starved for air. I have recently replaced the PCM because I had a problem with one of the injectors not working and it seems like it started after this. I went back to O'Reilly's and swapped it back out and there was not change in this after changing it out. Does the PCM have to be a special part?

Try having PCM flashed at Dealer to match VIN# & options, Good Luck

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
