5k rpm is late to start spooling, can you hear anything unusual like a leak sound?

 

[spikester603]

yeah revving the engine whilst stationary and letting someone try listening for a leak will not work as there is not much engine load, plus the noise from the motor will drown everything out.

Ive had this code P0134, my CAT element inside was spining around. The lamda sensor was then sending signals to the ECU to cut the boost. Car was slow as shit! Fitted a TP instead.

Good call on this, it's definitely a possibility!

get the car in the air, remove the two bolts from front of the CAT to the DP, have a look inside and see if you can move the element with your fingers. It could be the o2 sensor too, check the cable is in good condition..

Thanks a lot HappyMint, I am off to run some work related errands then hitting the dealership to test out the HFC cat (gonna take it off and check inside and hit the sensor connector with a rubber hammer as suggested). If that doesnt change jack, I will order me a new MFI relay and if that doesnt fix it either... I will just drive down to cobb @ plano (5 hours away) and get it all fixed.

5 hours?? I could drive through 5 countries in that time lol

good luck with your car:thumbup:

 

[spikester603]

have you tried driving the car and maybe see what codes you get again??

I still think its a CAT/O2 sensor problem.

My CAT was FUBAR and it just felt like my turbo was coming on late and not much power. Just because they look okay dosn't mean they are okay. My 3 MAF sensors looked fine......LOL

Them codes popped up for a reason buddy.

Multiple missfire code..

O2 sensor fault code...

and p0219 isnt a code you get when you remove the speed limiter (thats rubbish, I dont have that ever and my limiter is gone)

P0219 Indicates the vehicle has been operated in a manner which caused the engine speed to exceed a calibrated limit, is your car an MR/SST?

It will be something simple.

 

[spikester603]

P0219 on an MR is overboost I think? that would defo cause the symptoms that your describing.

I'm not an expert on SST's but that will need to be cleared from the ECU or your car wont boost properly.

Have you tried resetting the ECU? i don't know if this works with all codes??

also if it is overboost, you need to find out what's causing it? leak, cold temps etc... just a thought? i might be barking up the wrong tree here..

hope you get it sorted soon
