bill72 Member 4 Member For: 18y 1m 21d Posted 10/03/09 07:44 AM Share Posted 10/03/09 07:44 AM hi people`s, I have read some posts about idle problems good reading, but was wondering if anyone has ideas about this? I have xr6t had for 2years, its 2002 mod 4 speed auto, dont know if any mods been done but normally goes real nice, as the story goes just thought id try give it a little more oomf, installed after market cooler (monza) was going ok, but thought id put original air box back on as was running with pod, then I went for a test drive well gave it a big boot all OK until I stopped for traffic lights then car was idleing very rough, sounds like it is running on a couple of cylinders, I have only replaced coil packs about 6months ago,, car has only 75 thou on clock, what would most common fix for this?

Guest Guests Posted 10/03/09 07:47 AM Share Posted 10/03/09 07:47 AM Did it only do it quickly after you stck the boot in, then started idling normally again? If so, it's valve float & you are in need of new valve springs mate... Wouldn't be unheard of seeing as your car is nearly 7 years old & you just increased air flow through your system.

Guest Guests Posted 11/03/09 12:32 AM Share Posted 11/03/09 12:32 AM I'd be betting your valve springs have just gone 'soft' & you need new ones.Also, try replacing fuel filter Link to comment Share on other sites More sharing options...
