ok the car is a 2 ltr cab and it has been running ok ish ,three things were needing doing battery coil pack and plugs and leads.
so simple . on changing over coil pack after doing the air filter and battery , is seemed to run even worse . lack of power when putting foot down to around 3000 rpm...so took new one off put back on old one . here the odd thing it carried on running like this. like this .. so i changed the leads and plugs all correctly matched by direct motors , the fuel was very low so i have now added some cleaner in tank.. but still seems very fluttery..and ideas.
