Why is my 2.0 S 2001 golf when travelling around town or on highway the car hunts and jerks. When going on long trips and stop to refuel it wont start until it cools it wont start ?


run fault codes and look for problem in the ignition coil/s or ECM . This is a problem related to an overheating piece of electronic equipment like a coil, injector control , position sensor

Jerking when gas is pushed or in idle


It has been my experience with nissan that from your description, the EGR valve is bad."exaust gas recurculater" However it also may have a fuel filter issue due to perhaps water in fuel, trash,etc. If the engine operates correctly once you get it past the "shaky"area then the chances of the EGR valve being bad are better.
Hope this helps.....Good Luck!

I might have sugar or water in gas.


This is a Saturn ion i do not think there is and i would not even start this car if you even think there may be sugar in the tank,Water can cause a little damage but not really as long as there is gas mixed but still do not run engine. sugar is bad!!. this will cause lots of damage. converter, injectors and cylinder wall damage.
You will need to drop tank and drain it out and then flush it out good. then drain fuel lines and replace the fuel filter. after you are done i would put in a bottle of dry gas and a fuel injector cleaner additive in the tank.
Note ' make sure to flush tank good, When fuel lines are removed the fuel in lines should drain back out of lines. the only problem is what is in the fuel rail and injectors, this is why i said to add injector cleaner and dry gas additive to help if there is any small amount of water left in tank. hope this helps ,good luck.

3002 Pt Cruiser GT - 53, 000 miles - first start of the day - went about 1/4 mile down hill, engine light came on. Had put gas in the day before thought maybe the gas cap was lose. Tightened gas cap, went...


It sounds like a sensor is intermittantly loosing the data stream. Since the engine light came on, I would go to a reputable shop and have them check for codes. Many auto parts stores will do this as well and sometimes for free. Can't beet free. If I were to guess I would say something like the camshaft postion sensor is going bad, Or the crankshaft postion sensor, Or something like that. The code will tell which one it is.

Good luck, and if you have any further questions please....ask!

5 spd Pt will only push start after it was overheated. After push start it dies at idle. Timing? Will not battery jump start.


check to make sure your getting good gas up to the motor, take a screw driver and press the tip of it into the fuel pressure relief valve (it is one the side of the intake manifold, looks like a tire valve) gas should shoot out if it just drips out your not getting good gas up their and need to change the fuel filter and clean the injectors, also could be the engine coolant temp. sensor! If this don't work get back to me and I will tell you other things!

92 Chevy S-10 Pickup Will Not Start


good evening and welcome to fixya
im sorry to hear about your problem, not as much as you though im sure. you could start by checking the fuel injectors pulse width. you can rent a tool from local auto parts chain store or you can use meter. just unplug injector and hook pos, and neg up and try to start engine checking for volts, resistence and pulse width, it should send you quick signals like voltage spikes. it really sounds like you have an injector that is stuck open. this would cause the overheating issue because of the unburned fuel. have you noticed any check engine lights on? you can also try this push the gas pedal to the floor and whill holding it down try to start the vehicle by cranking it over for several seconds, this method will enter the computer into flood mode possibly allowing the vehicle to start. you can try cleaning the injectors really well along with injection system and air box very rarely does that work by have seen it work. You can rent a fuel pressure gauge from the local auto store also and check the fuel pressure at the fuel rail. check this things out when you get a chance and get back to me so i can help you further if you need. thank you for using fixya and dont forget to rate. good luck to you.



please rate this solution??
