Question about Hyundai Excel
Hi, this may be due to a sensor (PETROL ENGINE), (TOO MUCH FUEL and WETTING the SPARK PLUG) to check if the plug is black (UNBURNT FUEL). i dont know whitch sensor for sure, but, try this take the sensor CONNECTION OFF the AIR INTAKE (large pipe from the AIR FILTER), (MAF) MASS AIR FLOW. sometimes on various cars this will run o. k. BUT DO NOT BUY A (MAF) SENSOR BEFORE YOU CHECK the SPARK PLUG and TAKE the (MAF CONNECTION OFF). you can spend an awfull amount of money on sensors and is not fair because there are so many and to connect to the computer and get different results for sensors and (ECU) ENGINE CONTROL UNIT. many cars have gone to VAUXHALL MAIN DEALER AND DID NOT SOLVE THE PROBLEM they have the best of saftware and laptops. there are many quirky sensors on all of these cars. if this works, GOOD. SOME SPARK PLUGS have 1 SINGLE GROUND with the centre electrode and SOME have 2 or 3. the 3 grounds ensure the spark less likly to short (or foul) in the inside of well of the spark plug. it is very hard for us to determin faults because we do'nt see, hear, smell of petrol / diesel, we do'nt know how much you know, if you have the correct tools, we do'nt know if the tests we send your doing them right, we do'nt know if you have damaged any parts, you may be in the next street or half way around the world. thank for reading this. gerry
