ok before u guys say search and etc,i did and it was no help.

im having idle issues with my type r, before it was idling really high at 1.,500 rpms at a stop, then i adjusted the tps sensor, cleaned throttle body, and the flathead screw by throttlebody, not throttle cable one.

finally its back to 800 rpms as it is where i set it at, my bigproblem is....im crusing for example, im comming to a redlight so i put car in neutral, the rpms drop and stay at 1,500 rpms until i come to a FULL stop, then it would drop back to 800 rpms. cant be a vaccum leak because then it wouldnt drop down period. any help?? no checkengine light...(yes it works, because i unplugged the harness from tps sensor and CEL came on, plugged it back, it was gone.

 

BUMP ANYBODY!!??

 

hmmm that sounds intersting im trying to look something up for that

 

you using stock type r ecu or chipped p28?

 

What about your distributor? Once I purchased a car that did this and went through the exact same things you are, but I FINALLY noticed the distrubitor was all the way up. (If you notice the screw at the top of the alternator allows you to move it back and forth about an inch). Check that because mine was up all the way which was retarding the timing like no other.

 

Im having this is exact problem with my 2000 lx. anybody else had this problem?

 

i had a similar problem. check your intake manifold gasket see if you need to replace it.

 

im pretty sure it is not the IM gasket. I sprayed brake cleaner around all the gaskets and hoses with the car running and i didnt find any leaks.
