very rough Running

[B18 GPC]

My car has developed alot of "Backfire" popping .. and weird rattley , grinding noises on release of the throttle..

Only thing i have noticed is my fuel consumption is less.. and the engine returns to almost no choke straight after start up ..

the backfiring and poping , may seem more obvious because of the
exhaust [ (s) plural] but im sure its getting worse..

help Appreciated...

Nothing is due though.. the loud , crunching noise couldnt have been good..

Main bearings? Or something less sinister like a broken engine mount allowing movement, exhaust catching etc.
Check your exhaust isn't holed, failing that the condtion of your ignition system and air filter for the backfire popping. (If you have a big bore exhaust, it's relatively normal tho)

The exhaust it was ..

my dad came in and recond the crunchign noise was it vibrating on the rear axel .. i wasnt too convicence , but hes been a mechanic for 30 years now so .. his word for it :suspect:

Probaly where your new exhaust fouls it :D

Its not unusual for the standard exhausts to foul the rear axle when fitted slightly wrong so it is worth a look.

Which reminds me I must adjust mine to stop it fouling on the antiroll bar at the front. it makes a dreadful noise.
