I have been feeling my 1998 Range Rover 4.0SE missing usually when going up a hill, or sometimes even at 35 miles an hour on level ground, the check engine light came on. Took it to the same mechanic and he cleared the error so I could get passed an emission test, he said it could be bad spark plugs or spark plug wires or maybe a clogged injector.

I'm on a tight budget and still driving it, anyone want to take a guess? I believe nunber 7 is the drivers side by the firewall? Looks tought to take out.

Any tips would be great.

Clearing the code won't fix anything thing and the emission test will show the problem. That being said, go back and get the fault code numbers and get back to us, also, how many miles on the truck, when was it last tuned along with plug wires and what octane gas are you using?

 

Well, I have not gotten ahold of the mechanic yet to get the code, but I did go out and buy bosch 4 plugs and new oem spark plug wires, I finally got all the plugs out and it was number 7 that had the issue, the plug was not all the way in, it was kinda making a seal on the washer but the washer on the plug was not seated all the way down and it had blow buy around the spark plug.

Good news is now I have no miss fires and it has alot more power, now to just get that check engine light off, I don't think it will go off by it self.

Oh, I have 115k on the truck and I use premium 92 octane.
