No real power when driving up hill. EGR problem?

Hi All,

Just putting this out there for ideas. (And that I possibly may have accellerated the problem?).

Symptom: Nissan Almera 05 driving OK on the flat, but cant reach high speeds 80 plus.

Have to have acc pedal flat to the floor in third to climb a hill, and even then it only seems to just make it.

But engine not chugging.

A few weeks before this I put way too much oil in enginge and the exhaust was smoky for a minute or so.

Could this be the Exhaust Gas Recirculation valve need replacing?

Thanks for any suggestions.

No, not at the moment.

Yes, but not revving too much. Just seems sluggish.

Edit: Sorry yes, revs increasing, but no increased speed.

I put too much oil in my yoke and it had same problem a month or two later. Back in second gear to get up hills, no bother on flat.
The dpf wasn't regenerating. Change oil n filter n u might get away with it. If not diagnostic needed.

Thanks folks. I haven't got back to the garage again to have another look.

The garage couldn't find the problem at the time and I was to get back to them. Nothing was coming up on diagnostics.

Its grand on the flat, but when trying to go up a slight enough hill it just hasn't got the normal poke/lift in third or second.

I'll bring it back to the garage and ask them to check those things out. I sorta have this feeling that it might be something to do with when I put way too much oil in and the exhaust was chucking out black smoke for a few minutes.

That's why I thought at first it might be the Exhaust Gas Recirculation. But I'm guessing.

Thanks for those suggestions.

Hasn't it already been established that its revving out when you floor it and not going anywhere?
That's your clutch slipping.

Diagnostics wont see that.
A diagnostic by a mechanic trying to make the clutch slip will however show something.

I was incorrect. Revs are not increasing.

It could be the EGR. It needs to be opened to check for deposits. Cleaning may/may not help at this stage.

Any other symptoms?

No other symptoms whatsoever. If approaching and driving up a hill with speed it might make it but it struggles a bit.

If approaching a hill with little speed it just cant pick up. With a drop to second or third gear and it drives up a hill in slow motion.

No rattles? The exhaust system may have collapsed internally and could be restricting flow and not show up any faults otherwise.

No, no rattles. The car is running perfect apart from power going up a hill.

when you say way to much oil as in how much ? What did you do to correct it ?

I'm not exactly sure of amount of oil, but can check later.

Basically the car has been burning a good bit of oil. (It's serviced regularly enough).

Prior to a long journey, the dip stick was showing below minimum oil level. So I bought a larger oil top up from the garage, whatever that amount is. And put that all in. When I checked the oil level it was over the max level.

No action taken and car then went on 120 mile journey. Smoke from the exhaust for a brief period when driving off.

Car back in garage to see if we can get to the problem.

I'll let u know how it fares.

i had this problem with my 2002 1.8 automatic NISSAN ALMERA 2 door hatchback great little car went through everything
ie, petrol pump the line filter, even exhaust sensors , fi replaced the MASS AIR FLOW SENSOR , this fixed it

My hunch is that your're right, as my original feeling was that it was like one of the coils had gone without the chugging.

But to be honest it wouldn't take more than a beer mat to write down what I know about cars.

Park it up, put it in 2nd with the handbrake on.
Give it a bit of accelerator and let out the clutch.

The car should stall as you're letting out the clutch.

If it doesn't, it's the clutch.

Thanks folks.

Lots of great advice and very much appreciated.

maybe have the timing belt/chain checked - could be a tensioner about to give way, can be expensive to fix if it does. I know from experience and had similar symptoms before one went on a toyota deisel.

Egr has become the new Thermostat.
