The sound or drop in engine rpms doesn't happen on idle only under load. The noise sounds like a muffled grinding, maybe, but when it on the cars jerks really bad and revs drop low. If I release the gas pedal it stops and the car just cruises. I changed the spark plugged and the air intake, new air filter and ran injector cleaner in the fuel system. The oil level is good in transmission and engine. A mechanic suggested a misfire but there is no check engine light on, pluss it doesn't happen on idle. So far it seems to do it soon after starting to drive the car. I started the engine and let it worm up, drive in my subdivision for aprox 3 minutes and the noise and shaking was very bad but then subsided. It will still do it but not as bad while driving to work. One option is to drive it until it breaks down completely but I would prefer not to waste my money on a tow truck or unneeded repairs because this was not treated in time. Any advice is greatly appreciated. By the way, a friend connected a computer to the engine to see if there are any codes but none showed up.

gas gauge needle goes pass full

tire pressure light is on. Right rear tire and left front.

I thing that is that because mechanics things that

At times when I excelarate I can hear the grinding sound coming from the left front break side..

I need to know more about the check valves placed in the lubrication passages and other issues that can cause this abnormality. I tried changing twice the oil pump; All the crakshaft bearings are new; Changing twice oil filter; Checked the oil bulb; have install Pressure gauge with pointer and there´s the same low pressure.

Engine light is on. traction signal on the dash board. Sometimes it jerks when slowing down to a stop.

Speedometer reads higher than I'm going (~55, it'll show 90, or 120, or whatever it's in the mood to show, it varies, daily), it also shows 30mph, with car off & in park.

the car decelerates and a stabilize traction control message comes up on the message center
