Running super rich and melting down the honeycomb material inside the cat.

 

I am thinking the same thing here. I would love a temp reading off of them.

 

This sounds exactly like what I am dealing with, except I get a couple codes. It sounds like I have a few more fuel lines to examine. My evap system has a gross leak because of the lines alongside the fuel filler neck are corroded. I am putting in an order tomorrow for new ones, but first I will try to examine the line to the fuel filter. Please let us know what you find.
I have replaced timing belt, water pump, plugs, plug wires, ICM and thermostat. Under load/torque/hill it loses power and feels like surges in power. Also tried looking for intake leaks with starting fluid. I have noticed the vacuum pressure drops to about zero when the power surge begins. I am monitoring with bluetooth OBD and Torque Pro app.

 

Vacuum should be going down to zero when at wide open throttle. Max vacuum at idle, minimum at wot.

 

"mlduncan96" good that someone else has the same problem.
Today i am going to change fuelfilter and clean the gastank.
I also tried yesterday with another throttle body without any luck.

 

Nope, no luck with todays work.
Its only work fine over 4500 rpm, less its like chewing gum.
Crankshaft/camshaft position sensor maby?

 

Ronny, have you tested your throttle position sensor and MAF sensor? I'm not suggesting to replace them, just test them.

 

Today I took the time to do the compression test.
It was 12,2kg of each cylinder. Nothing wrong there.
It, however, I observed was that the intake gasket was greasy and it's very fouled in the intake.
I was out and test drove and when I got home, I checked the exhaust values.
145 HC and 13.8% co2.
After I had revving up it properly for a while became the values back to normal.
32HC and 14.9 co2.
It clearly has problems with combustion.
I'm starting to lose the desire to continue soon.

 

My new evap/fuel filler lines are on their way. Should be here by weekend. I was thinking of picking up a can of valve cleaner I saw on the local parts store shelf on the way home today thinking maybe a small deposit was keeping one from closing completely. After reading your post I am now wondering if this is a clogged catalytic converter. You have done far more than I have to determine what is going on.
I noticed my throttle body was very oily/greasy along with the intake. I wondered about the PCV valve. It looked rather dirty also, but seemed to move freely. I may go ahead and change it anyway since they are inexpensive. I had planned to clean my throttle body, but it didn't improve anything for yours, Ronny. I am down to thinking airflow backed up in the exhaust.

 

Where did you buy your EVAP pipe?
Last night as I stood in the garage and thought, and turned and twisted intake plenum, I saw that channel from the EGR valve was completely clogged inside the plenary.
It was a hell of a job to get rid of all the crap. It was completely blocked.
Thought I had found the problem, but no.
Exactly the same thing except to the EGR valve is working properly.
