1.6 Missfiring And Running Rough

[jameswallace. 8]

iv had a look through but i couldnt find anything similar to this!

 

the car wont hold an idle without a lot of throttle, the engine sounds extremely lumpy

 

it will drive but missfires loads at half throttle where as if you push your foot flat it seems fine its just miss fires and chugs along if it only had a little bit of gas

 

even with the foot on the gas it wont idle below 1500

 

iv changed the rotar arm, dizzy cap, spark plugs and coil pack and its had no effect

 

any ideas?!

have you checked all the pipes for air leaks? the afm ( air flow meter )? the sad ( supplimentary air device )? all of them and even the fuel filter can lead to poor running and poor idling! i am sure those more mechanically minded than myself could suggest even more things!

Have you just bought the car?

 

Check that the bolt that holds the oil filler to the inlet manifold is there and not leaking. This cause a problem for me.

 

Easy way to check for airleaks is to spray brake/carb cleaner on the various inlet pipes and see if there a change in engine rpm. (try to avoid spraying on exhaust manifold ect)
