that oil is on the MAF and IAT. if you dont clean them the problem will continue

 

done that its starts and idles for aound 7 mins then dies there is a rattle noise under the car

 

rattle could be anything. plugs are probably fouled. how did you clean the MaF and IAT?

 

i used electronic cleaner from my work i just put in new spark plugs i have uploaded a youtube video will get the link i check the coils with a spare plug and a spare ht lead not one for then sparked could be faulty lead or all my coils are done

 

this car has not run in 6 months and the battery is dead as soon as i get a jump it starts also in the video it died soon after

 

thats the video link

 

could this be my problem all my coils are working just found this i will attach a pic

 

looed at my cat after 5 mins of idling the car wants to die i looked under it and found the cat was glowing at two parts and it was bright red

 

no air out = no air in

 

Just remember, something caused that cat to go bad. It's still likely an ignition problem.

 

yeah i think it was the coils that caused it to go bad after a changed the plugs and coils the code for misfire went away now just need a new cat and i hope thats it fixed

 

another thing is she once the cat glows and it dies it wont start again is that normal for a failed cat

 

^yes

 

getting my cat replaced this week will let you know if she gets any better thanks for all the advice and help

 

Hey did replacing the cat help? Was it clogged?

 

This actually sounds a lot like my issue as well... did changing the cat help?

 

In my case the rattling was definitely due to pieces of the cat. It seems I actually have some further back, may be in my muffler cause I can hear them sliding inside when I stop and take off.
