This is odd but somewhat normal. This is the way the electronic gauges register. You can try to replace the oil sender to see if it registers different but as long as it shows some increase in pressure when you rev up you should ok. When you put in gear the RPMS on the tach will drop , thus reducing oil pressure. Also,not knowing when you changed the oil last you may just have worn out motor oil.

1989 Buick Lesabre Stalling When Putting in Gear


I have seen this happen when the ground connections on the computer ECM are bad. When the car is in park the ECM is not reading the oxygen sensors and when you put it in gear, it does. When the ground is bad, the voltage pulls back through the sensors because the original ground is bad. This makes the engine run really bad.

I have a 2000 dodge caravan. When the engine is running with van in park engine runs fine. When put into a drive gear the engine runs really rough and even stalls. The transmission fluid is ok. When the...


Sounds like there is a problem with the Torque converter in the transmission or Transmission itself. When you put it in gear it should initially go into neutral but occasionally the transmission will stick part way in gear and partially in neutral putting a load on the motor. It is not enough of a load to get the vehicle moving but it is enough to stall the motor. This could be a simple clutch adjustment in the Automatic clutch to a PCV valve issue to a need to rebuild the whole transmission because of a problem with the control body or transmission pump itself. Sorry for the bad news.

how did you clean the gasket off of the head? if you used a sanding disc the grit will eat up the bearings. are you reading pressure with a mechanical gauge? you have replaced all bearings??

6 psi @ 1000 RPM
18 psi @ 2000 RPM
24 psi @ 4000 RPM
this is chevrolet specs on oil pressure in your truck so you are within the range.

Need help on a 1995 Chevy Suburban. It will die at idle when it's up to running temp and in gear. I have to pump the gas peddle to keep it from dying. Just did a tune up and throttle body cleaning to see...


it sounds like the motor's tick over is far to slow when the car is put in gear if the tick over is say 750 rpm out of gear then it stalls when you put it in gear lift the tick over up to say 850 rpm the best way to set this up is have a friend sit in the car, warm the motor up, then get your friend to hold the foot brake hard on and put the car in gear, if it stalls bring the tick over up (in gear) till it dont stall,,,but hold the brakes hard on when your doing this,,,getting run over is not a nice thing to hapen to you and it wont make your day? you should feel a dit of a thump when you plop it into gear so hold the foot brake down when you do plop it in gear every time you do so, it saves the transmishion getting a thumping, all the things you have done to your car so far have only done it good, but why not change the oil and filter as well and know you have done the full monty on your car, and it wont need another service for another year or so?????

Vibration when in gear, and stalling.


The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

Check your fuel pump presure. Pump is in the tank. Also try and loosen the fuel cap, the tank vent may be stopped up.
