3800's are really good motors, but that's a sign of fuel injector problems. I've seen this all to many times. Run some injector cleaner through it and see if cleans up.

One question however, does it stall out and have a problem restarting? Black smoke out of the exhaust? This is sign of an EGR valve problem that may be fixable simply with a nice cleaning.

I'd try the injector cleaner first, and if it continues, go onto the EGR valve. If this shows no problem, it may be a good time to take the car to a mechanic and have the injectors tested. They may be failing but not giving out a fault indicator.

sounds like you have a problem with the head or head gasket.Pulled out the spark plugs and see if you have any showing signs of leakage from head/gasket.

The fuel filter is located in the pressure line that runs from the fuel tank to the engine, near to the fuel tank.
Keep the engine off for few hours before replacing the filter, to get rid of some pressure in the lines.

yes it can mix, also check the timing cover for rubs from the timing chain. this is the common problem with 22r. many mechanics will tell you its the block but they are just trying to make money.

SOURCE: I have a 2000 monte carlo ss 3800 series.

The problem might be your Vats security system. This causes the car to either "not start" or "shut down" while running, or start for 5 seconds and then die. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year.

Cheap fix: Bypass the chip in your key. Temporary, but effective.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of their page.........

----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites

2004 monte carlo ss 3.8 engine diagnostic message "cylinder 5 misfire"- will changing the spark plugs resolve this issue?


it is a good place to start, replace ignition wires and plugs, for that year 3800 i recomend autolite iridium plugs and premium 7MM wires.
once you replace the parts erase the code and see if it returns.
cylinder 5 is the 3rd counting from the left on front of engine.

Have a 2003 monty carlo ss. I have had to get system completely flushed 5 times keeps getting gunked up. It's only been six months and I have to get it flushed again.Service engine light also stays...


If you are talking about the coolant system there are a few things that cause them to get gunked up. I have found most of the time with the 3.8 liter and 3.4 liter motors that the intake gasket is leaking and allowing oil to mix with the antifreeze and I have also run across people mixing Dexcool and regular green antifreeze and that will cause the cooling system to gel up also.

I have a 2004 Monte Carlo SS, while driving I lost all water and it over heated. turns out the frost plug at the front of the motor (block heater one) had blown out. I never saw any leaks on the ground...


your main concern right now is to replace the frost plug and while you are at it flush the engine then fill with proper anti freeze mix, you should be good to go

My car is leaking oil, it is from the basepan. Is


By basepan, do you mean the oil pan? The 3800 engine in your monte has problems with the pan gasket leaking, or the pan itself rotting. You can do it yourself, but it requires either lifting the engine up about 6 inches, or dropping the cradle.

If you can do that, then yes, you can change it yourself, otherwise, you will need to take it to the shop. I've done 3 of them and it is a pain. Unless you're really into being a mechanic, take it somewhere.
