rough idling and ignition switch

Recommended Posts

Hi all,

I have been having two problems with my 987 and I hope you guys may have some ideas on where to start diagnosing.

1. The car idles rough on inclines. It idles perfectly on level ground but when is stopped at either on up slope or down slope, the idling is not happy. I am stumped.

2. The ignition switch. It takes a few jiggling counterclockwise or taking out and putting in again for the car to fire up. Sometimes the steering wheel lock doesn't release but sometimes it does and it still doesn't fire up. After a few tries, then the 987 starts. The dealer said 987 ignition switch is different from 986 and said the 986 switch problem doesn't affect it. They kept saying change out the car battery first. However, I never have a slow crank issue but simply nothing is happening except electrics on when ignition misbehave. And they mention the ignition switch failure should throw a code inside computer which I kind of doubt....

I hope to get some ideas from fellow 987ers. thanks

HI...

Do not have any Boxsters. And I don't have an idea about #1. On #2, did they say to change the car battery or the Key battery? Sometimes if the key battery ( a small watch battery) gets weak, it can case starting problems due to the transponder setup that the car reads when the key is used. May be worth checking. Just a thought

The dealer mechanic was referring to the car battery. The key remote so far has been operating perfectly so I doubt the battery is weak. However, I'll change it to see if there's an improvement.

Any update? Did you change your KEY BATTERY? Any change in condition? Let us know what you come up with....

Thanks,

sorry didn't update as I want to try it out for a week before I conclude anything. I changed the key battery and so far is operating perfectly and I am hoping that's the issue. I would have never thought is the key battery because I always thought the key battery is only for the remote and not affect the ignition. It wouldn't be good if the key battery goes dead and car wouldn't start....

As for the rough idling on inclines, took it to the dealer and they couldn't observe it nor any codes could be found. The engine never dies out but the engine just felt rough at idle on inclines.

Thanks

Quick update.

The intermittent ignition switch problem came back. The battery is brand new. Took it to dealer and of course it doesn't misbehave there. They pulled codes and couldn't find anything. It felt like the immobilizer is simply not recognizing the key when this issue comes up. Mechanically the switch can still be turned on but the electronics is simply dead. Usually a few key reinsert will get it going but it once took me 5 mins of trying to get it going. I wonder would pedro's DIY article apply (on the post 2003 cars)

Yes, it sounds like the electrical switch is broken on your car. The 987 actually only has an electronic switch - no mechanical links to it. The steering lock is controlled by an electronic solenoid-type box (good luck if *that* fails). You should be able to simply pull off the rubber plug, and release the nut underneath to remove the switch. Here's a link to my article, but the 987 is a lot simpler than the 986: http://www.pelicanparts.com/techarticles/Boxster_Tech/86-ELEC-Ignition_Switch/86-ELEC-Ignition_Switch.htm

Dear Wayne,

 

Do you have some graphics, or pictures about how to remove the ignition switch in a 987-1?

Thanks in advance,

Rodolfo.
