Hey
Need some help. My car has started missing like a mongrel. Seems to coincide with me using 2 tanks of Vortex 95. Could be a coincidence.
Has new fuel pump. Had problem with stalling and had new air intake sensor put in. Still stalled but not as much. Seems to be starting better and goes along well till I start to accelerate then chugs along then comes good when hits the speed I want. Any ideas of things I can try at home would be brilliant cos sick of chucking money at the mechanics down the road for it. Thanks

How old are the spark plugs . Crook plugs can cause a miss under acceleration . Plug leads can cause it to . Cheers Ken .

Plugs haven't been changed since had the car - bout 2 years lol... might try that thanks.

If the spark plug thing doesnt work there is a few things i have done to fix miss firering 4 liters. I have an el and had a few probs in the past. Is ur car on gas?

No isn't on gas mate. I changed the plugs and ran good for a while now is chugging and rockin like a bastard. Just went out and cleaned the air intake module as this helps when its stalling, checked the plug leads and 2 didn't seem to be down far enough. Shook out the air filter and gonna buy a new one today. Took it for a drive and running a bit better but still missing. Do u reckon new leads? Am a poor woman home mechanic trying to save a few bucks cos sick of being ripped off. Have fixed a few things on it and saved some good dollars. Fixed the brake pedal switch by myself and discovered a fuse gone in the motor when the whole car died on me while driving one day lol. Imagine what that would have cost me! Any more tips of what I can do would be brilliant. Thanks

I had a similar problem with the wifes EF turned out to be crook leads

roony38 · 06-03-2009, 03:06

thanks. Know this probably sounds dumb to you all but when u check the leads by taking off one at a time do you turn the car off to stop the sparking before u put them back on?

No you don't have to stop the motor to put the leads on unless it's going to give you a shock .
If the car has done a few km's and you have never had the leads changed it would be a good idea to do them .
If you do them your self just do one at a time and you can't go wrong .
The other thing to check /replace is the coil .
Cheers Ken
