....being afraid to drive your newly purchased 1988 911.

Twice in two weeks as I was driving...once after 30 minutes...once after 4 minutes......the eninge just shut down.....like it was out of gas....pulled over to side.....wouldn't start....waited 5 minutes.....it started....

after searching Rennlist...I have clue it might be a DME relay.....one was last replaced...3-07.....

any ideas out there...just got my car July 2 after waiting 45 years....help...Dwight Johnson

yeah many are gonna chime in , and even if you get one and it doesn't fix it , it is always great to keep a spare in the glove compartment.

+1. DME relay is easy to check. Clean your grounds, and on the 3.2 911, the postive battery clamp goes bad and eventually needs to be replaced. We did a Rennlist no start checklist previously. You might want to look for it. On Pelican, there are a few knowledgable guys on the 3.2. I'd google Ischmitz because he's good and very helpful. The 3.2 911 is very bulletproof, and one of the most reliable cars you will own.

DME relay symptoms

g-50cab

The carreras are pretty simple compared to modern cars - the DME relay is a known trouble issue - keep a spare - the other two main items that have issues are the cylinder head temp sensor and the flywheel reference sensors - they tell the DME brain what to do next. They reside in not the greatest environments - so it's common for their coverings to get cooked.

From there - Idle control valve - tends to stick. last but not least is the Bosch Barn Door air flow meter. It can get gummed up - the sensor can actually wear a path in the sensor media and cause problems.

This problem did not occur during your PPI???

many possibilities,...settle down and work with these posters...don't freak out.

I've found the "experience of the walkthrough" with the fellow posters is one rewarding process..


deep breathe,...get started.

Best,

worse than no 911?

I'd say uncorking bad bottle of 1990 LaTour or '82 M/R,..yet you'd get over this with time.



...as will the car part of the worseness.

Best,

Dwight Johnson

The prize goes to g-50cab. Looks like it might be the flywheel sensors. But now I need the Bosch #'s to cross reference and find the same part for the 1990 M3 BMW....same part but half the price. Anyone help here? Dwight

am I to understand this is 9 months later and still not resolved? has the car just sat all that time?

Hope you found the problem!
