recently I have had a hesitation problem and a holding back problem I have now found the fault I hope. would a leaking inlet manifold gasket cause a hesitation problem oh its on a 2wd cosworth

Ollie.

Yes. I had a similar problem with my old 4x4 and once the new gasket was on it felt like a new car....

spray wd40 along the manifold to see if it IS leaking!

my one is popping a little. and some times whistle and my boost has also dropped from 2bar to 1.6 I sprayed crab cleaner on my suspected area and the revs went up .a new gasket and a plenum spacer would do me nice

*Bri.4.b.Cos*

I use carb cleaner to check for inlet leaks as above if its leaking revs pick up

Never done no harm on cars, but me bike was addicted to it lol

why no carb cleaner ive never had a problem

Alvyn

iTrader: (1)

because it COULD catch on fire due to the ignition leads etc which are under the manifold

changed gasket and it fixed my air leak. but the hesitation problem is still ther it does it low rev and when flat out other wise if just crusing the its fine its like i get to pops then fine agine every time i lift of the throttel

Basky

have you checked the plugs
running an air leak can cause it to run rich there for fowl your plugs
