I flooded my rx7 from not letting it warm up, fulled the injection relay and cranked over put relay back in and it started.Now i have found under load the car is cutting like a fuel/ignition cut any ideas as it is fine if i rev engine up at idle or whilst driving but as soon as i put foot down it starts cutting and back firing... any ideas?

 

fouled plugs.

 

cool thanks i have just ordered some new ones hopfullt this will sort it i did remove a couple plugs in the weekend they were black but didnt look as bad as i thought they would if they were fouled

 

I had the same problem, but the plugs were not fouled... Is you problem right around 5k?

 

Na its as soon as i put my poot down flat its fine if i put pedal down half way will go right past 5 k, im guessing the extra fuel/air is just to much for the weak spark

 

Don't wanna flood, don't have a rotory

 

I wasnt aware that they can flood so easily will let it heat up from now on..... was just asking round to get some ideas on problems after flooding and car running rough......

 

could be your leading or trailing coils that are not sending enough spark to the plugs...

 

Could also be that your trailing ignitor is going bad. It happened to mine and swapped a new one in and bingo, all running smooth.

 

lol what?

 

changed the plugs last night found that one of the lower plugs was loose as running fine again cheers for the help!!
