my tigra has developed a judder when im accelerating. it recently had head gasket,cam kit, water pump, bolts,caterlitic converter. it was driving fine for a while before juddering occurred. its been on diagnostics and all clear, there are no warning lights on at all. 1 garage said blocked exhaust, another said dropped valve or coil pack.is there anyway to tell without spending stupid money. as the car has cost me double what I originally paid. any1 plz help.. many thanks
Running Rough, Starting & Power Loss
Possibly more of an ignition issue such as coil,leads or plug,s surprised no codes logged ,really need to test the car and look at parameters to see what,s happening,a good garage may be able to do this.
