Rpm gauge dropping to zero while cruising in car

Hi! I have a 2000 Grand Prix. While I'm cruising the RPM gauge drops to zero the car jerks and the trac off light comes on. A couple of times it has cut out on me when this has happened. Also, most recently, after shutting it off and then trying to restart it would barely do so, like it wasn't getting any gas. Happened twice in the last week. Any ideas why this is happening would be appreciated. Thanks, Gloria

    My 2000 Pontiac Grand Prix GT would stop/die while driving, any speed and at any time. Had the Mass Air Flow Sensor replaced, car has not died since.

Oil pressure gauge drops to zero when car slows down, sometimes will go up when rpm reaches 2800, otherwise stays at zero, when shut off and turned on again pressure would be normal

Hi assuming the oil filter has not become blocked, it sounds like the oil pump is not working properly. Of course it could be something more simple like a faulty gauge, sender or bad connection. But assuming again that the engine is suffering from oil starvation, I would get it checked quickly before you seize the engine completely. Good luck!

First off, is a check engine lite on,if so do you know the codes?It does have a cam sensor,the cam sensor malfunction gives a code reading,in general fuel probs do not give a code this is done bymanually checking fuel press ect....the module does give specific codes as well...I have seen a cam sensor give the prob. you list, BUT TEST BEFORE YOU BUY,you can get your own codes from the a.l.d.l connector,under dash...take a coated jumper wire and push one end into the g .circuit ,the other into the b terminal and watch the lite flashig in the dash,,ie, 2 flashes...pause then 4 flashes is an example....wilf

Have the fault codes read. Replace faulty items. Use only genuine items as non-genuine replacement are not always compatible with the OEM fitted CPU units.

2004 Pontiac Grand Prix Temp Gauge not working and car not running properly.

I would check the coolant temp. sensor it should be in the head and have one wire on it. The manufacturers program the computers to change the air fuel mixture, and idle higher when the engine is cold. If the engine is at normal temp and the computer thinks its not it could be idling it up to bring it to proper operating temp.

My 1999 grand prix boggs out when I rev it up to 4000 rpm how can i fix this ?

first thing to do is to scan for codes(hard codes) if no codes test fuel pressure and flow. You also can check for exhaust restriction by hooking up a vacuum gauge and watch it at a steady rpm, if it starts to drop back suspect restriction (ie) cat breaking up or inner pipe collasped,or impact to exhaust

The abs light and the trac light come on at the same time. right after I take off. the rpm is way high when it shifts and does not shift into overdrive.

I literally just had this problem solved. The cars computer was giving a code for bad intake or something like that and I just cleared the code, its running beautifully now!

I have a 2005 Chevy Uplander, and when driving on the highway at about 60-65, the van occasionally drops RPM's and when you press the gas harder, it recovers without any jerking or anything. The same...

This is a rare one and can be tricky. Since your rpm gauge rises back up when you increase your acceleration slightly but you feel no jerking of acceleration then this tells me that a speed/rpm senser either has a bad connecton or the sensor itself is going bad when the engine reaches an optimum heat while driveing on the highway. Since you feel no acceleration when you slightly press the accelerator down but yet the rpm gauge is increasing back to normal, the throttle body sensor may be compensating for the failed speed sensor/failed sensor connector. Please get your uplander diagnosed properly first to confim this.
