Its been maybe over a month my car has been broke down. No one can figure out what's wrong with it. It all started when I changed the spark plugs. Had to replace a boot Ans coyle then the car starts surging and Bucking and driving like crap..we changed egr valve the fuel pump fuel filter now I took it down the road today and the engine light started flashing..which I didn't know what it meant but knew it was bad. I looked it up and it said a dangerous miss fire? My.next guess is to change all the boots and coils what do you all think? The car has no power and it surges and jumps around going down the road.
I'm a angel in ariat boots and a devil in blue jeans. I'm every cowgirls nightmare and every cowboys dream
If it's the car in the picture, there aren't any wires, just COP's. You could have damaged one when you changed the plugs, they can break when you pull them off. Happened to me with my 03, had to replace it.
Take it to a good shop and have them test the coils. I have a tester at my shop that all i have to do it put it over the COP and it will tell me if its firing. Dont forget injectors though, they will cause misfire as well. Make sure all thr connectors are connected securely. Sometimes they look to be but arent. If any of the securing clips are broken ziptie them secure and test. Injectors can be tested the same way as the COPs with the right tester. Sometimes its cheaper just to have the right tests done rather than throwin money at every other part in the car
put a scanner on it (free at most auto places dont pay for it to be done)
it could be the coil you installed is bad~ or another one is bad. I would recheck the install of the coil and look at the plug to see if its good as well make sure the end of the plug is all there and looks good.
