The car has no problem starting up when the engine is cold. Its having a problem starting ONLY when the engine is warmed up already. I try starting it about 10 times within 15 minutes, and it starts up. Once it starts up, the car starts shaking like crazy and feels like it is about to die. I give it some gas for a bit and everything is fine. What can the problem be?

 

that was happening to my girls car. we used BG 44K enging cleaner. similar to seafoam but much stronger. and her car started to run fine after about 15 min of driving.
