Engine starts and idles fine but bogs out and dies at 1500 RPM.  

 

I pulled the timing belt covers off to check the timing marks on the cams and it "looks" like it's still right.  Swapped out the cam sensor to see if that was the problem but no change.  

 

When idling the left cam pulley looks like it might be wobbling slightly but could be an optical illusion. I checked the pulley to see if there was any play but it was solid. Any ideas?

I would suggest pulling a couple spark plugs and looking to see if they are covered in fuel or not, also check the plug gap. Another piece of information is what plugs do you have in it? Some are known to cause problems.

 

Then go to your MAF and airfilter. Get a can of MAF sensor cleaner and clean the MAF sensor(even if you don't have a code, its still a good idea to do on occasion). 

 

Also check fuel pressure as engine rpm is increased, pump might not be putting out enough fuel as the demand is increased.

Fuel pressure 32. Swapped MAF and ECU. No change. New plugs. No change. All vac and pressure lines attached. New timing belt. No change. The only thing I've found out of spec is IAC resistance. 10.5 instead of 9. Would this cause the issue or am I missing something.
