Got 02 4.3 RS2 just got done putting heads on it. Shows im at 12-14 degrees advance. Seems to have a slight spark knock and a bit lazy. Anyone have experience with this problem.

 

Did you set the CMP Retard to zero after installing the distributor (details in the Tech Article section)?

 

No I didn't. Sorry to be a pain if the information is already here I'm new to your site obviously. And to this truck. Thanks for your response.

 

Check out the EDI Engine Timing thread in the Tech Article (DIY) section. The index of this section is linked to in my signature below.

 

Right on I just read it. Didn't think that bracket was sloppy enough to get 15 degrees but will have try that first. Dont have scanner that smart. Or do you disagree with that line of thought.

 

You'll need a scan tool to accurately set the CMP Retard to zero. The only other way is to trial and error it until its running better. Even then, you'll want to get it on a capable scan tool to get it as close to zero as possible as premature cam & distributor wear can occur with prolonged run time off zero.

 

Will do. Thanks for your time

 

Thats much better thanks again.
