Targa Top Noise
Anybody experienced a targa top (glass) creaking and groaning after bumps on rough roads? Seems to be coming from the attachment points. If so, anybody know a cure?

Re: Cleaning engine parts.
I recall something about not using Simple Green or other chemical cleaners as well. Have not heard about the fine polish before. Anybody else have any knowledge/experience?

Pizza Box contents
Anybody know a complete list of the contents of a 90 pizza box? Did it include the hardcover 32 page book and the Drivers manual?

Re: Code 31 - Camshaft Sensor
Actually got a referral to the Fuel Injector Connection today and ordered a set of the Delphi replacement injectors. They are supposedly prepped for direct installation, flow tested and matched. They...

Re: Code 31 - Camshaft Sensor
Are the Accel 150821 injectors still the choice for replacements? From the research I've done, they appear to be direct replacements.

Re: Code 31 - Camshaft Sensor
Well Tom, looks like I'm not that lucky. I serviced the sensor connector as you said, checked and cleaned the MAP sensor hoses, reset the ECM, and got the SES light back when I restarted it. Got the...

Re: Code 31 - Camshaft Sensor
So I assume you have to take the aluminum cover off to get to the MAP hose?
Thanks for the advice on the cam sensor connector. I'll try that.

Re: Code 31 - Camshaft Sensor
Thanks Tom. When you got the 31 code did you just clean the harness connector up near the brake master cylinder with dielectric spray or something similar?
I don't think it's injectors as it ran...
