Chevrolet - Montecarlo :: 2003 - High RPM Random Misfire
Here's the deal with this car i just did head gasket, valve job, all new intake gaskets and spark plugs. Car idles fine and mid throttles fine but with high throttle it wont shift and flashes the random misfire light p0300 it seems to run out of power. I've heard everything from maf sensors to ignition coils and wires. i was just wonder a good place to start and good test to do. I have most testing equipment including scan tool so i can ride with it. o and all cylinders compression tested above 150.....

2000 Chevy Monte Carlo... The heater/blower only works sometimes, usually not at all when it's freezing out. when it's a little warmer out, it tends to work more often, but still not all the time. what could this be? my husband tried replacing the blower motor, but that didn't change the situation, so he put the old one back in, and is now puzzled ?

2000 Chevy Monte Carlo 3.4l - The problem that I currently have is that the car will not idle smoothly, it bounces between 600 and 800 rpm. I have replaced the spark plugs, wires, fuel filter and thought I checked the hoses. Just got done changing the upper and lover manifold seals, during which I replaced or cleaned what ever was suggested by the place I purchased my parts through. I am at a loss, I have begun to notice that there are small fluctuations on the highway when I am using the cruise control and am on flat land.

My poor 2000 Chevy Monte Carlo SS is turning into a hooptie. Or at least it sounds like one. I am due for a front brake pad change in about a month, so I'm wondering if this new noise has anything to do with it. If not, I certainly hope it's affordable!
And now to the strange noise being emitted from the front of the car. This morning, about 50 degrees, I started my engine to drop my boyfriend off at work. While idling in the parking spot, I heard a dim car horn - fog horn combo noise. A neighbor gave me a "wtf" face, and I'm sure I returned her stare with the same expression. Hoping it was something else, I drove off.
First stop light, just down the block, while idling and waiting for the light to turn green, I hear the same noise. Very embarrassing. Next light I stop at, same noise. Once the car got to half of its optimum temperature, the noise stopped and didn't return.
That is, until several hours later when I needed to go to work and restarted the car from a cool nap. Same noise.
So, what the deal is? I thought it might be fan related, as it kind of sounds like there is some rattling going on in there, too.
Chevrolet - Montecarlo :: 2000 - Driver Side Axle Seal Leaks Fluid Only After A Drive
I have a 2000 Chevy Monte Carlo that has me stumped as to why it leaks. The driver side axle seal leaks fluid only after a drive. I have replaced the axle twice and seal 6 times and it still leaks. I am stumped on this one. Unless I got a bad axle twice that the diameter of the sealing surface is too small but didn't seem like it as the seal hugs the shaft.

I have a 2000 Impala with a 3800 V6 series 2 with 165,000 miles. The only code I had was a P0300 Multiple random misfire that occured off and on at first, Worse in the city Better on Highway. It would start running on half the cylinders and bogged down, with the check engine light flashing, after getting onto the highway it would straighten itself out at first. I thought i had water in the gas so i ran some heat through it. straightened out for a day then happened again so I thought maybe a should run some premium gas in it, The car ran like total crap until the premium was gone, so i thought maybe it's running too rich, I put 87octane in it and it ran great for a day or two, then it gradually got worse to where it would not straighten up on the highway, tried to die at stoplights and i had to drive it with 2 feet to get it home and park it. I've replaced the battery, spark plugs, wires, ICM checked good, coil packs are good, replaced fuel Pressure regulator, looked for arcing on the spark plug heat shields and it will not start. It turns over but doesn't try to ignite and when I get the slightest rumble of ignition, it backfires up through the manifold and I see a puff of gas or light smoke by the exhaust manifold.
The car had a vacuum leak around the intake manifold cover gasket and a leak on the fuel rail. I pulled the fuel rail off my impala, snugged up the rest of the intake bolts then disassembled the fuel rail, flushed it out and cleaned the injectors the best i could, then reassembled it. before i re-installed the fuel rail I hooked it up to the fuel lines outside of the engine and tried to start the vehicle. all injectors had a nice spray pattern. So i installed the rail and it still didn't start but it had more combustion than before although it's still backfiring like before. Checked the fuel pressure by turning the key on and the fuel pressure went to zero very fast. I blew the rail out with air so to make sure i didn't damage the regulator I replaced it with the old one, ran the test again with same results, so i reinstalled the new regulator. I performed the fuel pressure test a few more times while moving the fuel hoses and when i moved the back supply line the vacuum loss stopped then dropped to zero when i let off of it. So I replaced the fuel line connector and O-rings on the injectors. It no longer has a vacuum leak.
I cleaned the EGR Valve out and had no luck there, then I removed the Idle Air Control Valve-pushed the pintle in, re-ionstalled it and WooHoo! it started! Although it still ran like crap with the same random misfire I was still happy to hear it start.I pulled the plugs on it to do a compression test and all 6 cylinders have between 180-190psi so the engine is in good condition mechanically. I installed new plugs before getting the car restarted and when i removed them for the test they were covered in thick black soot after running for roughly 15 minutes max.
I have (2) 2000 Chevy Impala's so I've swapped sensors from my wifes car to see if it would fix it. I've tested the following MAP, MAF, IAC, coil packs and ECM. None of these made the car change. I believe it is a timing chain because the car has never had a new timing chain and is way overdue, but I haven't had a code for a crankshaft position sensor. Can the timing chain be bad without throwing a code? It's not out of time enough to change the valve timing because I had a good compression test but its not firing right and still has the multiple random misfire. I have not checked or received a trouble code for o2 sensors, crankshaft position sensor or cam sensor. Something has the timing retarded and is dumping extra fuel into the engine because my new plugs looked like they were in the engine for a year.
Chevrolet - Montecarlo :: 1995 - Won't Start Intermittently
i own a 95 monte carlo z34. ever since i bought it last yr. i have had starting problems. i thought it might be a fuse, checked them all and there fine. i noticed when i pluged in the 2 ingnition fuses back in the fuse block under the hood,the security light lit up for a min then went out. now my car has the chip in the key also. i thought the securty system is failing some how. might it be the tumbler in the colum? if so i read here it could be bypassed, by buying a resister, and spliceing in to a fat orange wire under the steering column, to by pass the security system. is it that easy? if the person who posted the ad with the same problems im haveing could give me more detail instructions on doing this my self,because id rather fix it than take it to a dealer and spend big bucks i don't have.

I have a 2001 Monte Carlo that I absolutely love. The check engine light has been on forever, despite repairs that should have turned that light off. Just recently, my car has started to gain RMP while I'm stopped or going anywhere between 0-25 miles per hour. This also makes the car physically shake and jolt. Very unfortunate. I turn it on to drive once more and then my check engine light flashed and beeped at me. I thought about waiting to take it in until Monday, but now I think it is best to bring it in now.
View 4 RepliesChevrolet - Montecarlo :: 2003 - Popping Sound Only When Turning Right
I found a steal of a car for my son, a 2003 Monte Carlo SS. The car had been hit slightly in the LF corner. The car needed front brakes, so I bought a package off Ebay that had rotors, pads, and wheel hubs. I replaced the LF wheel hub when we did the brakes and kept one for a spare since the RF felt good.
Shortly after replacing these parts, the car started to make a popping sound when you would turn right. The popping sound is much like an exhaust pipe dragging on the ground. We checked to make sure the was no contact with moving parts. After reading several forums, we decided to replace the LF hub with the spare we had. This did not fix the situation, so we put the first replacement LF hub onto the RF. Still no fix.
After this we decided to take the car to a empty parking lot and drove in circles trying to find the source of the noise. We discovered that the noise would go away if the car was put into neutral. We were still unable to locate the source of the noise.
So I decided to jack the car up and put it in gear and turn right. The noise did not occur with no load on the tires. However the u-joints on the axles were making some excessive noise, so I put in a new set of axles. Again this did not fix the noise. Now thinking the source must be in the differential.
Well two days after putting in new axles, the transmission went out. This will surely fix it, right? Well the mechanic that fixed the transmission said the pump had gone out, and it appeared the differential was creating shavings that caused this situation. GREAT WE FOUND THE SOURCE. Not so much!
Car still makes noise while turning right after replacing the transmission. I have driven myself crazy trying to find the source of this noise including riding in the engine compartment while my father drove in circles in the local high school parking lot.

Chevrolet - Montecarlo :: 2006 - Ticking Noise Coming From A/C?
I have a noise coming from the interior of my car that is incredibly, amazingly, terribly obnoxious. Not to mention somewhat embarrassing when I have a passenger, and it decides to show off.
Part of the problem is that it's unpredictable when it will occur. It could go weeks or even months without making the noise. Out of nowhere, it will start up again and continue once or twice day, or even any time I start the engine.
The best way I can describe it is: TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK
A brief pause of maybe 5 seconds....Then: TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK-TUK
If I switch the blowing knob from the driver setting to, say, feet, or dash, it'll stop for a moment and then resume with the TUK-TUK-TUK-TUK-TUK
After it gets as many TUK-TUK-TUK-TUK-TUKs out of its system as possible, everything goes back to normal. During this process and afterwards, it blows cool/hot air at the correct setting, so no performance issues.
Car in question is a 2006 Monte Carlo - Any possibility this is a relatively simple DIY repair? I'm comfortable with basic tasks like replacing car stereos, speakers, headlights, oil change...If this'll require much more skill than those sorts of tasks, I'll likely need to put this repair in the hands of a professional.
Chevrolet - Transmissions - Montecarlo :: 2002 - Hard To Shift Between Gears
I own a 2002 Monte Carlo SS 3.8 6cyl. I believe it has a 4T65-E transmission.
On a regular basis if I drive 20 miles out of town, on my way back the transmission starts to shift hard (long shift?). From my research online, the 4T65-e is a faulty transmission to begin with. Is it worth replacing the Shift and Pressure solenoids? If I were to buy a new transmission where should I look? What are some model numbers?
Oil, trans fluid, filters are changed on regular basis.New catalytic converter. No Check Engine Light.

View 5 RepliesChevrolet - Montecarlo :: 1997 - Engine Randomly Has A Miss When Cruising
When cruising my engine randomly has a miss. If I step on it, not necessarily full throttle but some, the engine pulls fine no miss. I don't think it's ignition because it doesn't miss with increased throttle. I have looked at an analyzer and none of the sensors is showing a fault. I have put 20 tankfuls of fuel with cleaner through it after I put a new fuel pump and filter on and I only use Shell now for the last 10 fill ups. The miss is not a passive drop in rpm but more of a buck.

View 3 RepliesChevrolet - Montecarlo :: 2002 - Temp Gauge Bouncing From High In The Red To Low
I have a 2002 Monte Carlo what recently had a new radiator, thermostat, intake manifold gaskets replaced. I was spewing coolant everywhere. Since the repairs with all new OEM parts, I still get the 'Hot Coolant Temp" warning on my dash. The temp gauge is pinned at 260 but minutes later drastically drop to under half way after which it seems to balance out at slightly under half way.
I also see the 'Low Coolant" as well even though I am full. All of this occurring while driving. I checked the oil and underneath the oil cap. No frothy or milkiness. Exhaust seems ok, no white smoke. The heat inside my car when i run it seems to go from warm to cold and back again. I'm praying it's not a cracked heard or blown head gaskets.
