Hi newbie here,

Bought a W/2000 100sx today for my mother.

Have a slight problem. Car starts fine from cold. Once warmed (so expect auto choke is no longer working) the idle sits fine - but when I go to give it a little gas it cuts out unless I give it more gas than it needs over revving- this happens when sitting from idle in neutral - it's like it's hesitating - this also happens at junctions or indeed whenever the accelerator is depressed in any gear at any RPM - obviously when on the hoof it just chugs a little and sets off.

This is a problem when slow manouvering tho and is quite dangerous - junctions etc.

Also during a run out the car cut out at a junction - when restarted the temp gauge sat at the bottom on cold? and it didn't raise for a few miles - but the engine was defo hot.

I've time on Wednesday to look at it - was gonna give it a service anyway, oil, oil/air filters, check/replace plugs, check fuel filter and flush out coolant system.

So... was wondering if anyone has come across this issue.

I thought of a sticky throttle body - or maybe air temp/coolant temp sensor. As said will check plugs and will run some injection system cleaner through it anyway.

Lastly - an ancillary is making a high pitched whirring related to RPM, so something is stiff and resisting the force, I don't want it to get fatigued and break... so any ideas. I thought water pump maybe.

Thanks in advance for any help you can offer.

Hello , i had a prob with bad idle/excelleration , it turned out to be my battery being far to small ,after asking advice here i also reset the system by disconnecting the battery for an hour odd , changing the battery/disconnecting has REALLY made a difference , you'l get a more informed opinion when The Beast, Bulldog, Dave are back on in the week-their the real experts , wish you luck
