325_driver 422 Report post Posted February 3, 2008 hey guys got a new e30 320 shell manual yus ! doesnt compare to the 325 manual i have any way took it for a blast, didnt hammer it, but it seems that when ever i seem to accellerate heavily or heavier you could say and it gets past a certain rpm (2000) i think it seems to cut out, splutter, grunt, power loss, etc etc so i can go arround accellerating carefully or else it feels like theres no guts left sound like a fuel problem? Air ? electrical? the dash board is not plugged in, have anything to do with it ? cheers Quote Share this post Link to post Share on other sites

325_driver 422 Report post Posted February 3, 2008 will do, could the car not been running for ages have any thing to do with it ? empty gas tank with time would it rust ? just thinking out side of the box here Quote Share this post Link to post Share on other sites
will 169 Report post Posted February 3, 2008 Fuel pump could be on the way out, also could be a blocked fuel filter. If you can clearly hear the fuel pump running while the car is idling, it is a sign that it is on its way out. It should run almost silently. Check that the petrol tank vent is open, if it is blocked, it will pull a vacuum in the tank and starve fuel under demand. Take the fuel cap off and try it, if it cures it clean all the spiders/whatever out of the vent.. HT leads can also cause problems, check the resistances across the leads, should be <10Kohm. Replace if greater. Will Quote Share this post Link to post Share on other sites
325_driver 422 Report post Posted February 4, 2008 took fuel cap off, no difference still gets upto x amount of rpms and cuts out so just to narrow down the problem a bit more, i rev it and when it gets to a certain rpm it cuts out, splutters you could say. im gonna take some pictures of a few things and any one let me know if i need to pay attention to, e.g. theres some thing in the throttle system ive never seen, since i normally drive the b25 motor. ill get some shots now Quote Share this post Link to post Share on other sites

tcbaurpower 5 Report post Posted February 5, 2008 Hello. That is the cruise control as i dont have that. I had an idle problem when i first got the e30 325i and all i did to fix it was clean out the air intake around the butterfly value. Also the flexible pipe connections when loose also effect the flow, check that they are all tight. Cheers Quote Share this post Link to post Share on other sites

That is an idle stabiliser, prevents the engine from cutting out if you blip the throttle or take your foot off the accelerator suddenly. Won't cause the problem you are having. You may have a faulty air flow meter, see if you can borrow one from someone with the same engine as yours.

325_driver 422 Report post Posted February 7, 2008 thats cool. i have an identical 320, will see if when i swap the afm over if it stops the problem what else do you reakon it will be ? could it be fuel pump ? or tho i do find it wierd that it cuts out only at a certain rpm like there is no problem accelerating to that rpm Quote Share this post Link to post Share on other sites
