I checked the solenoid for the right side variocam. Ohmed out the coil...16 ohms.

I think the coil is ok. I guess it could be a wiring problem with the solenoid or the sensor.

Any common places for these wires to get pinched? Thanks

The more I read the more I think my problem is a variocam actuator.

Car does rattle a slight bit when rpm goes up, but smooths out as RPM increases.

My understanding is that the timing is advanced all the time when the variocam solenoid screws up...as they need to

have oil pressure from the solenoid to shift the timing chain to retard the timing.

I also understand that it can be replaced without removing the engine...anyone ever done one? Thanks

OK pulled codes with the code reader again.

I have read that the O2 sensor can cause missfires in one bank of cylinders...Any help? Thanks

O2 sensors do not cause misfires.

Looks to me like you may have a cam position sensor problem.

All your faults are on bank one of the engine (one side).

Further investigation is warranted - and the car should not be driven (or run) as it is now - or more damage may be done.

I swapped the cam position sensors from one bank to the other. (left to right and right to left side)

Now I have

suburban99, did you get a Pre Purchase Inspection (PPI)?

No I did not. Car was bought as a project.

I figured if I bought an old chevy I would be working on it too.

Car was well priced.

Thanks for the reply.

Cam position sensor...I will check tomorrow to see if it's unplugged...any way to test it off car?

Another question may be related or not...while I was fixing the spoiler switch I noticed that the bottom

row of relays above the fusepanel does not have any relays in it. As well the heater fan does not work.

The defrost switch is illuminated all the time so I thought maybe the countdown relay was missing? (just a guess)

Do you know where to get a picture of the relay tray with their intended functions?

Again thanks.

Sepentine belt came off yesterday. Idler pulley bearing seized and thru off belt. Hauled car home on my trailer as I did not want to overheat engine.

Replaced all the bearings in the idler pulleys today ($4.00 each) and put belt back on.

Car has a slightly rough idle after warming up and check engine light comes on after driving for about 4 miles or so. P0300 is the only error code I can pull with my code reader.

Do I need to buy a different one or am I not doing it right? Any help appreciated.

MY half day old Boxster did the same thing yesterday. Idler pulley bearing let go., and the sepentine belt came off. Hauled car home on my trailer. Took off both idlers and replaced bearing, about $4.00 each.

Remove the bulkhead cover and have a look. Good luck.

Hey guys. Just bought a 1997 Arctic Silver Boxster. 5 speed About 100k on the clock.

A couple of questions.

Air Bag light is on-I plan on reading up on Durametric software and possibly purchasing it.

Check engine light was on, I pulled a code po300 from it and reset it. The car ran out of fuel on my test drive.

I understand this to be misfire. Hopefully it was just the fuel. Only pulled 1 code from it.

The electric defroster switch is uliminated all the time.

Where can I get an owners manual preferably PDF and free? I have seen a 99 owners manual online and downloaded it.

Currently trailering car home. Thanks
