Cold running problems
hi guys, my car was running real lumpy when cold so i changed the.
1. maf sensor 2. coil pack 3. coolant temp sensor after changing the coolant temp sensor it ran like a dream for about 4-5 days and now AGAIN it is running really lumpy when cold, as soon as it warms up it fine. the coil pack and the maf was second hand when i got them. any idears what els it could be. Thanks David |
i took the car for a long drive to marewell zoo today and noticed that when its cold its realy lumpy and when its warm i thought that it was fine but i was wrong and its not.
even when warm it still hesitates and some times missfires, it also seems to be holding back quite a bit. Thanks David |
manifold / intercooler leak causing maf measured air to not enter the engine and the ecu injecting fuel for it.. therefore running rich
check intercooler pipes and vac lines |
