hi can anyone help i need to change my ht leads and plugs i think the car is not running very smooth just got from london and the ride was horrible its very shuddery and when you put your foot down it will sort of miss then get going i have changed the air filter  still the same can anyone help ive been looking at the leads but how the hell you change them is beond me where do thay go to at back of engine where do i start

Are you sure it is the leads??has the car raised any eml lights??? if so would be worth doing the "paper clip" test to read them..have just had similar issues with mine and it was the throttle position sensor,but in view of the cost of ht leads and the issues with their replacement ,would make sure that is the cause      

[Markie]

more than a strong possibilty its either or a combination of all....

spark plugs
leads
dis pack.

Basics first.

Take the leads off at plug side and check for oil in wells, check for oil around rocker covers, and inspect the leads that you can get easy access too....

After that come back and let us know what you find.

 

[magnaman]

this may sound silly but how do you do the paper clip test and there is no oil or gunk around plugs

[magnaman]

i did find very small amount of oil in each ht lead where it plugs onto plug cleaned these but still the same

[Markie]

okay...paperclip test s a method of using a paper clip to short inthe fuse box to provide fault codes...i`ll post the link to it shortly.

Oil in plug wells is never good - do you know when the camcovers were last done?

Does it idle okay  - nice and steady?

Oil in plugwells WILL`destroy the ht leads, do they look brown at the plug end?

[magnaman]

the car idles very well nice and steady there is no oil in the plug wells it sounds like the car is missing if i floor the car it wont pull then all of a suddern she goes i got new set of leads so am going to replace these anyway  thay look old but how do i get to back of engine i can get to all plug ends but cant see where other end goes any pics

Go to DIS behind cylinder 6. Tight, and probably needs to be done by feel.

[sassanach]

how are you getting on with the leads?

[magnaman]

getting mate to do it it needs to be running before next weekend so i can go on holiday(cornwall)

[sassanach]

while your in there take out the dis pack and check it for delamination,as that might be your real problem

[sassanach]

sorted yet?
