Hello everyone,

My alfa 1.7ts 1994 150.000km has the following problem: when the engine runs high revs +4000 for approximately 15 minutes the engine wants to stop, the problem is solved when the car is stopped and run idle for a couple of second then run again without problems for approximately 15 minutes. The dealer checked the electronics but these seems to be ok, my idea is some kind of fuel problems :(
Has anyone had these kinds of problems?

Regards

Rene

I would guess a blocked fuel filter. Or it could be a faulty fuel pump.
Does it do it at ant engine temp, or only when cold or hot ???

If it splutters first, its usually fuel, but if it just plain dies, it's likely electrics. I might suspect something cheap first, like a relay!
Keep a log of conditions, this will help!

Oh yes. Remember Marlon's suggestion of a fuel pump. This is fairly likely, and could save a lot of aggro later. I've seen the pumps go faulty before, and intermittently 'stall' until the power supply is cut, and then restored.

I only drive these high revs when the engine is hot so i don't know if the problem occurs with a cold engine.

But thanks for the replay

The engine stays on and has never dies during this problems, a couple of seconds low revs are enough to solve the problem up to now!

Had some problems on a friend's car. Nobody NEVER EVER found out what the problem was. Well at last, after changing, both fuelpumps, fuelpipes and filter, I took out the fueltank... What did I see? A freaking small bolt, that came into the pipe wich made the car stop. When we waited a little while the vacuum wasn't that big the bolt falled out into the tank again, and no problem.. Just a nice story, eh? :p
Just a thought if everything else fails... Wich I don't believe. Bet it's the pump...

Thanks for the reaction,

First I am going to change the fuel filter and if that would not solve the problem I'am going to remove the fuel tank,
according an other member there is also a possibility that there is dirt in the tank.

Rene, while your at it, check for signs of water around the pick-up in the tank. That one's a favourite. (BTW, water collects at the bottom in a petrol tank.)

Hi all,
I thought you would know about the methylated spirits thing. A little meths in the tank ( for memory about 1 cup for 1/2 a tank of fuel.) The meths mixes with the water and burns off!! Easy!! :)
