Default Hesitating cosworth off-boost..........

Hesitates and holds back on light throttle/just after gear change etc

Is this just a low-comp/BD10 problem or should it drive as normal?????

Had injectors ultra sonically cleaned/re-conned over the winter,the base Co was 8% when I re-fitted them,set it to 3% and thats when its started this hesitating/holding back

Spec is:low-comp,BD10's,big valve ported/polished head,Stg3 MSD chip,
T34.63.

Thanks Kev

Which injectors are you using? Could be too much fuel,or too much fuel pressure or maybe even throttle position sensor. Or even coolant temp sensor. Its hard to say without actually looking at the car

had the same problem with mine, took it to powers 2day and they found out that when u rev'd the car the voltage droped to the fuel pump casuing fuel starvation. So have to replace the wireing for it. Could be the same thing, or just a sensor as said best to get it looked at really mate!!

Yeah will get it booked in

Runs fine on boost

Bit thirsty too,86 miles to £20

Fitted new water temp sensor couple months back,also if this was gone would'nt have been able to set Co at idle correctly.

Thanks
