All,

Been having a problem for quite a while now, when the car is warmed if I blip the throttle the engine stumbles slightly by 200ish rpm. This is also directly linked to my hesitation problem when fully warm.

Any ideas on what this could be?

Thanks.

apologies for not putting the details;

EG6 SiR, b16a.
Mods: I/H/E/VAFC. Car returns 32-34MPG in town, new o2 sensor, has had a full tune up recently, new HT leads.

Only thing I haven't checked is the dizzy internals, and Fuel. Timing has been checked (although didn't have the service connector on when I tweaked it).

when is the last time you cleaned your intake manifold? the inside of it?

check ur dizzy good ! i had a similiar problem and changed my entire setup on my dizzy but to no avail. then i pulled the dizzy and found the shaft bearing to be blown out in it. also replaced my map sensor and tps sensor too b4 i did the dizzy swap and it slightly fixed it but not all the way.

the engine has 59K miles, I havev't actually cleaned the intake mani inside. In Regards to the dizzy, is that inside the dizzy itself?

Update* Changed IAT / TPS for new ones and still have the problem!
