Question about 1986 Chevrolet Chevy
I agree that you have replaced all the possible causes for car misfiring,but did you checked voltages at all the parts.It should show exact 12 volts.If its less then that then there is a short in the connections or the parts replaced are not connected properly.Check out all the ignition coil/injectors one by one ,this will confirm the fault.Also get the fuel pressure checked.If its less then fuel pump and fuel filter needs to be replaced.---------
The car starts but misses and runs very bad this indicates that an ignition coil or spark plug may be failing or a fuel injector may be failing. Also check in the gas tank .Is the car running out of gas. Check if car is running out of gas or low on gas , dirt in the bottom of the fuel tank, clogged fuel filter, and clogged injectors. Replace fuel filter and pour a bottle of fuel injector cleaner in the gas tank.If all the above mentioned possibilities checked out OK. Then Get the car scanned at diagnosis center. If the problem repeats again n again then its advisable to get car scanned at diagnosis center to get error codes, At diagnosis center you will receive the error code.As per the error code it will detect the exact faulty part in the car due to which the problem is occurring.For more help :--- at www.autozone.com its absolutely free to get car scanned.
