Hi my car is a Chrysler - Stratus 2005 it has 77,000 kilometers anyways over the last couple weeks it started making a clicking sound when you start the car there is no noise it takes a couple minutes of driving before it starts and it only starts clicking when I am not pressing the gas pedal for example when I come up on a stop light and lift my foot of the gas pedal the noise starts and when I turn off the car it gets in it's last few clicks real fast as the engine shuts down

I was told it could be the transmission or the motor

was told maybe it is the type of oil I used I had an oil change and had them put in the best synthetic oil they had that was acout 2 months ago or about 1,000 miles the mechanic said maybe my car doesn't like the synthetic oills because they are to thin so again I just had another oil change this time using regular oil which was thick and some oil additive to help compression and stop noises anyways needless to say it stoped the noise for a couple hours but today the noise was back 100% I was told it would take a few days to eliminate the noise but it is just as bad as before anyways needless to say maybe it is not the oil and maybe you guys have a better idea of what it could be

before I go through an expensive motor or transmission repair maybe it is something else

by the way I am in mexico who knows how good the mechanics are that I went to which is why I am asking you guys I went to 4 different mechanics all said it sounded like the transmission so I went to a transmission specialist he disconected the transmission and had me run the motor with out the transmission conected and he said it was not the transmission cause he still heard the clicking although I could not hear the clicking at all hardly he said that was because the weight of the transmission not on the motor is what made it rattle less but also after he connected the transmission agina it took about 5-6 hours before the noise came back again

Please Help by the way this is all I have on my paypal account at the moment which is why I am only donating $2.90

Hi Miguel, Randy here. The first thing that came to mind from your dandy description is the emissions system purge valve. It sits near the right side of the engine and under the right conditions will pulse or thump about twice per second. It is possible to hear it inside the car. You will feel it too if you hold your hand on it. The fix is to wrap it in foam rubber to block the noise.

The engine computer pulses this valve to pull stored fuel vapor from the charcoal canister to be burned in the engine. This does not occur until the engine is warmed up.

Interesting approach for your mechanic to disconnect the transmission. I assume he removed the bolts between the flex plate and torque converter. You might want to consider a crack developing around the bolts where the flex plate is bolted to the engine's crankshaft. This doesn't exactly fit your description, but if it is the cause, it will eventually get worse and could cause a banging noise. Disconnecting it this way would make the noise stop because there would be no force on it from driving the transmission.

It may be necessary to snoop around with a stethoscope to find the location of the noise. Also look for a chirping serpentine belt or a noisy pulley.
