Hi guys,

I just started my car today and it started right away. Instantly I noticed that the Vaccums were at 12inhg which is quite low and the car was idling rough... So took the plugs out to find one plug had oil and fuel on it... I changed the plug and the car started up better and I got 18inhg stable idle but not for long within 5 minute of idling the problem came back and the car become rough and vaccums dropped to 10inhg and the car wanted to dye...

Where should I start... I am using a power fc and my knock sensor is also not worrking.. Will work on that monday...

Any thoughts on the above would be greatly appreciated... Thanks

 

stuck open injector is a possibility.

 

Thanks.. Will check that out tomorrow...

 

Hey guys.. I always like to post when the problem is solved... It turns out that the plug wires were connected in the wrong sequence... put them in the correct sequence and the car is rock solid and is pulling around 19inhg.. is that ok?

 

Ok seems I spoke too soon... Plug wires put right the car idled amazing... I took it for a short drive and it ran great... So I left it at the garage for a wash and some small things to do... I also told them to let it idle for 30 mins.. They kept movin the car to and from the garage and the body shop and it ran perfectly.. Just in the evening when I was about to goto pick the car up they were letting it idle for 30 mins and the problem came back... The vacuum drpped from 18 to 10 inhg.. I am too tired now what to do.. I am using old spark plugs I am going to try new ones tom. And also check if the injector is stuck..

Any ideas guys

 

What mods do you have again?

 

Just intake, exhaust and power fc...
