Car Shutters Around 3000rpm

[matthew0786]

My series 2 has been shuttering for a couple of days now. The car will drive fine for about 1hr and then when i drive off from a stand still, the car will be hesitant to move and it will jerk back and forth. Also my fuel pump (Bosch 040) is really loud when this happens

Does you boost gauge jump back and forth when this happens?

[matthew0786]

i'm not sure, when this happens im too busy worrying whats happening around the car so that i dont cause any accidents. Right now its in the garage, might wanna investigate and fix before i take it back on the road again

Sounds EXACTLY like what happened to mine a few weeks ago. Series 2 with a bosch 040.....fuel pump crazy loud...fluttering loss of power. Turns out the fuel pump was shagged and was losing fuel pressure ...and this was a 9 month old pump. When I took it out it was all corroded / oxidized. Went cheap and whacked in a stock pump for the moment and all's well. Dunno if I got a dud pump or what but looking for something other than bosch now.

Interesting coincidence. My pump is around 9 months old too. Just happened all of a sudden. Now what should i do? should i buy a Walbro?

Hmm, Does it keep building up revs after its past shudder point or does it refuse to go higher?

i'd replace the fuel filter first:P $14 gogo

take of the coil pac cover and get a multimetre and make sure all read 1.7Ohms...if not it could be one of the coil packs

for the fuel pump, is it easy to remove and check it ? if its makin' a loud noise and never did ur guarenteed thats the issue

i suppose i should try and do all those. I had a feeling it might of been the coil packs. Ill might go change the fuel filter as well. Thanks, ill keep yous posted

the car shutters during 3000rpm, then i shift up a gear, and 95% of the shutter goes away.

if the fuel pump is making noises when it does it then it is going to be something to do with the fuel system. it could possibly be the fuel pressure regulator.

im currently running the stock fuel pressure regulator.

i do however have a Sard Fuel pressure regulator that is not in use. What kind of sealing do i need to use when i connect those 2 pipes (not the fuel hoses) to the regulator? After i connect the fuel regulator, would i need to adjust the fuel pressure or do i just leave it? Cheers.

Ahh hold up, 1.7Ohms?? I got readings from 1.2 - 1.9, could the ones on 1.2 ohms be fugged?? (my cars slowa atm)
