99 metro 1.0 5 speed, car has been running great and getting aroung 43 to 44 miles per gallon. But yesterday i was coasting off my favorite hill to work, push the clutch in and coast the motor dies. When i let out on the clutch it will start and run just fine, also when i am running at a steady pace i can let up on the gas while still in gear and it will take about 3 to 5 seconds before it will catch and take off. The car has 160,000 miles and the fuel pump is the one from the factory. Could it be the sock around the pump is getting clogged up ? thanks for any help.

Before throwing parts at it, perform a compression test on the cylinders, test spark, test fuel pressure.

Check Engine light on? Get a scan.

Does it idle just fine?

Not sure if I understand the symptoms: "push the clutch in and coast the motor dies. When i let out on the clutch it will start and run just fine".

BUT 1st thing that comes to mind is to check for cracked/broken/disconnected vacuum lines.

Could use more details, and a scan would most likely point you right to the problem, but it sounds to me like a bad IAC solenoid or perhaps the TPS. If I was throwing parts at it an IAC would be first on my list.

i changed out the distributor cap and got new spark plugs and it drove good, that was until yesterday going home from work, the temp has been in the 60s or so until yesterday when it got up to 85 and it did it again. i will test everthing and repost the results, thanks

sounds to me like a short to ground somewhere on the ignition circuit in conjunction with the clutch pedal position switch. try shunting the CPP closed (you can start without pressing the clutch so keep it in N ) if this confirms the problem or eliminates it. i would inspect your inside fuse panel connectors, pins and contacts also take the clamshell apart and look for burnt or damaged busses.

ok JOHNNY , i ran the codes and i got a p0135 which is o2 heater circuit malfunction bank 1 sensor 1 and a p1250 and i think that is the pre heater for the fuel to warm up on a cold day under the throttle body i think. The compression was 155 to 160 on all three cyl. so does this mean my front o2 censor is bad ?

couldn't hurt to change out your 02 sensors
