poor idle and acceleration '93 9000 CSE Posted by turbosaab [Email] (#9999) [Profile/Gallery] (more from turbosaab) on Wed, 7 Jan 2004 07:10:26 Members do not see ads below this line. - Help Keep This Site Online - Signup |
My '93 9000CSE has a rough idle problem - the RPMs will dip and sometimes it will stall. During acceleration it often stumbles pretty bad, like the engine is momentarily cutting out, it will do this in rapid succession and make the car jerk. Started as a very intermittent problem and has gotten progressively worse over the last 400 miles. I tried swapping a known good DI cassette and that didn't help, tried a can of Berryman's B12 in the gas, checked the plugs and they all look pretty black.
The only known problem is the wastegate rod has fallen off the turbo and I haven't put it back on - so it is only at base boost. It has been like this for a couple thousand miles. might this be causing the poor running?
Thanks,
Franz
