Title: Can anyone help mg zr
Post by: rikki_essex on 24 October 2009, 17:06:19
On idle it is all over the place and when reved it doesnt come down as quick as it should. Also some times it will rev up to 3k on idle and back down and some times cuts out. Any ideas????

Agree :y take a can of carb cleaner and spray a small amount on each area, the revs will rise with the alcahol in the spray. You'll soon find it :y

I think all the 1.8's are K series engines mate.

Until they are modded, they eat HG's for breakfast, lunch, & dinner  ;D

i would deffo say K series, would get somebody to do the sniffer test on the coolant system (any reasonale garage with a head gasket leak detecting kit) can do this for you, if not headgasket i will be suprised indeed, and as said poss air leak

easiest way to tell if it is a K series the engine number will tell you should be on the log book

right a family relation came down on the off chance and he said he had the same problem on one of his motors so he took out the idle control valve or something to that effect cleaned it and put it back in. Problem fixed.  :y

Yeah, sticky idle valve on K series is the normal cause for eratic idle. All petrol ZRs (and 25s) are K series, and suffer the HG problem due to lack of engine development when under control of the germans.

It would appear that the MLS gasket along with the new ladder does cure the HG issue.


Guess what I need to do on her 25 ::)
