Title: misfiraring at lower revs and backfiring at the back of the exaust system
Post by: michaelb on October 04, 2015, 05:37:12 PM
Hi All

It has been a while since I have posted a tread on here, I guess I have had no issue with the car until now:

I have 3 rg  generation tween turbo with nice supporting mods.  Recently when I step on it at lower revs,  occasionally I have loss of power, car seems to misfire and lots of backfiring at the back.  If I claim slowly to ay 4k revs and then step on it in any gear car behaves fine.  It only happens at around 2.5 k 3.5 k and only when I accelerate hard.  As I said if I accelerate moderately then step on it at say 4 k all is well?
Any ideas ? Spark plugs ?  Coil overs ? Ignition issue ?

I may have to take the car to Hayward Rotary..  Engine has only around 1k if not less on it since the rebuild...

Regards, Michaelb

Plugs or fuel filter I would guess,
