Engine running issues - cut out up a hill - problems!!!!

[kelvingenders]

Hi all, just having some engine running issues with my 360 GLT B200E engine

When I drive up a road in 3rd or 4th, the car is tending to max out at 200-2500 rpm, with no power. It's feels as thought it is surging. For example, the car will not go over 70KMH unless going down a hill.

Could this be cause by the MAF sensor? or a faulty fuel pump. or any other

The other day while going up a hill I had to drop back into 1st, the car spluttered and nearly stalled, tick over when to 600rpm, then revs picked up again and it got me home.

Anyone got any clues what's is causing this problems

When was the fuel filter changed? Also spark plugs?

[kelvingenders]

Engine bay one - 2 years ago, only done 2500 km. Fuel tank one - same time. Spark plugs - same time

[Logan360]

What about cleaning/replacing distributor rotor/cap?

[kelvingenders]

Brand new ish...I rebuilt the old beast about two years ago. I'm going to change all cheap parts, fuel filters first

[Logan360]

I've got a spare afm or two if you need one. Have you run injector cleaner through? Maybe its just blocked or dirty injector's

[kelvingenders]

Replaced injectors - all new....thinking it my be crap fuel....

[kelvingenders]

Hi Logan, got two spare MAF units, think they are all in similar condition.....hope it's not my ECU playing up. I'll let you know the results

Ignition breakdown will be fairly harsh, engine will feel really rough when its happening.

Sounds more like lack of fuel, I'd go for the AFM, but you might want to check fuel rail pressure (regulator and pump), and of course post measurement air leaks, breathers etc.

You could try rigging up an external switch for the cold start injector, that will give you more fuel (as an experiment).

Putting a new fuel pump in this weekend....

[kelvingenders]

Turned out the external fuel filter was completely blocked..... a new ryco z153k filter...beast is running fine again

[Ride_on]

Is this the pre-pump filter, apparently more of a moisture trap or resevoir than a filter, but I'm not entirely sure. If you fit a normal filter it will cause problems for the pump, especially at lower tank levels.

[kelvingenders]

Yep, pre pump, it's a cheap paper filter and is really there to trap crap, but allows lots to fuel to flow.

I'm thinking of draining the tank and seeing what other crap comes from this area. Will update soon
