i have had this cavalier for 15 yrs and it finally had an intake gasket coolant leak that showed up on a bitter cold day in winter.  i waited till weather improved some and pulled it down to find issue then left it that way for over a year. finally had to fix or junk so i got the parts and did the job and when i got it running it was flooding out. that was a yr ago now and i’m ready to tackle this new issue now. i had went check for codes but no response from computer. i had never seen a check engine light so i pulled dash and bulb was gone. installed bulb and tried again thru key trick and nothing. so put reader on port and no response. i cant believe car runs at all without computer involved? and i dont even know where it’s located to check for ground and power. only reason i keep car is cause it’s the GENIE convertible.

Placed in Drive car felt like it was going to lurch/jump forward and made a loud noise.  check engine light is now on.  Engine was cold.  Checked all other gears they felt fine and was smooth.  It only has happend in Drive.  Checked gears after I got home from work.  ALL the gears felt fine and smooth.  Automatic transmission.

What would cause this?  Should I be afraid to drive to work tonight?

I have been working on the engine in my blazer for a few weeks now. I started by getting a crank kit to put in it and replaced all the gaskets when I put the engine back together. I got everything put together and set the timing and got it started. I noticed that after I started it that I have a slight knock coming from somewhere on the driver side of the engine. I first thought it was from the fuel pump but I removed it and started the engine while it was off and still had the knock. The pistons and ring are in good condition the valves and push-rods look good. I adjusted the rocker arms to specifications listed in my Chilton manual. I am currently waiting on a rebuilt carburetor to arrive because mine sat for awhile and doesn’t want to work properly. My question boils down to what can be causing the knock in my engine.

The van started knocking and would not gain speed. It was winding out the gears before shifting. Then a heater hose blew and I lost all antifreeze. Got the hose fixed and think that the oil pump is bad. But not sure about it not gaining speed and winding the gears out. What could the problem be.

I own a 2001 chevy tahoe Ls 4wd 5.3 liter I was wondering if it’s normal for the 4wd shaft to turn when driving and 4wd is not activated ???

if you put gas in the carburetor it will start and run fine. go to start it later and just cranks. replaced fuel pressure regulator still wont start
