Hesitant Valver - Urgent help needed

[James Clio 16v]

This morning I drove my 93 Clio 16v to work as normal, 40 minute journey, fairly heavy traffic. On a few occasions the car felt as if was going to cut out, like the car was running out of petrol, it was a bit hesitant. The engine speed was around 4.5-5k.

What could this be?

Is it the start of fuel pressure regulator problems or am I looking at something electrical?

Or could it just be bad fuel?

Any suggestions would be most welcome.

Thanks

James

When did it do this?

Throughout the trip or just when cold/warm?

 

[James Clio 16v]

It was doing it throughout the trip.

I have just had a look under the bonnet and the engine sounds as if it is hunting/misfiring, not a lot just slightly.

I am wondering if I have a fouled spark plug or if the dizzy cap is tracking.

Doesnt sounds like any of the commen valver engine faults to be honest so hopefully itll be something simple like a knackered lead or what you have said.

 

[James Clio 16v]

Yeah, I hope so.

Im having a new ps pump fitted on Wednesday & thats gonna cost enough!

Exhaust Gas Pressure sensor, or something similar (Common / Known fault on newer clios), gives symptoms similar to those youre describing, - happened with my old 1.2 Y reg. Just a thought.

worth changind the fuel filter.

Fuel filter was changed back in March, but Ill do it again just in case it was crap fuel.
