Strange problem with engine starting
Hi
For some time I have a problem with engine starting. When the engine is cold in the morning, for example, the engine starts right away without any problems, but if you take a ride a few miles and then try to start the engine again the starter motor spins a long time. When the finally ignites then the engine speed increases up to 2000 rpm and then slowly drops to 1100 rpm and the car is ready to drive. I replaced the spark plugs and battery but it did not help. I've read a bit about it and think that the issue can be caused by damage one of several engine sensors (MAP, coolant or crankshaft), but I do not know exactly how to find a faulty one. Any ideas? I will be grateful for your help.
