Default Cam timing was out.

I think, since the car is running a little better, that now would be a good time to check your timing. I know that if one of your camshafts is just a tooth off, it will run similarly to what you're describing.

Remove the plastic upper timing cover, and verify that when the engine is at TDC on the compression stroke the 2 cam gear timing marks point straight up, inline with the raised line on the timing plate behind the cam gears. Also make sure your crank is pointed right at the 0 mark. If not, release the belt tension, slide the belt off the cam gears, and adjust as necessary.

Once that's all dialed in, replace your timing cover and idle the car up to operating temperature. You're gonna put a jumper wire in the diagnostic box (like you're checking for codes), hook up a timing light to the no.1 cylinder wire, and set your base ignition timing to 10? BTDC. Make your adjustments by loosening that dizzy bolt and turning it till it's set. Once dialed in, tighten the bolt, remove your jumper wire, disconnect the timing light, and go for a drive.


Let us know how it drives then


Oh, more detailed instructions on checking timing can be found in the TSRM
Just wanted you to know. I have been on IR and just now checked cam timing. Right cam off by 2 teeth. Improved performance. Can't thank you enough for your advice.
