First start up of the day is fine. After its been driven, sometimes it wont start unless I pump the gas pedal while turning the key. Car runs fine, but sometimes while stopped at a red light it stumbles like it wants to turn off and sometimes it does. When it occurs too much, I spray the throtle body intake and it seems to do the trick but only for a few days. I've changed fuel & air filters, spark plugs & wires, O2 sensor, cleaned fuel injectors, egr & pvc valve. Fuel pump makes its electrical hizzing sound when key is turned so i take it its working fine. I havent learned how to check for vaccuum leaks. Repair shops dont mention the minor possibilities, they right away suggest the most expensive repair, fuel pump.

The coolant level indicator on the dashboard is always on despite having the radiator and the resovoire filled to the brim

Hooked a meter to the chip of the car key to check the resitor.What should the reading be on the meter ?

I am worried that i will get pulled over for not havving break light on the rear except for the one in the back window that does work. Can anyone help me with my problem?

Car started running rough and sound terrible. Check engine light came on and started blinking. Got it home put a code reader to it and got P0303 and P0300. I have changed the spark plug and wires, replaced the fuel injector, and replaced the fuel filter; still having issues. I cleared the codes with the code reader after making all the above repairs....turned on the car and the check engine light began blinking again after a few moments. Engine sounds better but the P0303 and P0300codes came back. What could the problem be now? Ignition Coils?

Pulley is out of alignment with the other pulley can I push the pulley back into alignment.
