You had no misfires prior to installing the injectors
so what ever you did caused this not bad coils
it’s easy to get coil wires mixed up to the correct plug double check wires from coil to spark plug

 

X2 on this. After doing all of my engine work the other weekend, I felt a misfire as I drove off. CEL finally came on, then flashing. Cyls 4 and 6. Realised the wires were about the same length and swapped them from plug to plug. No more misfire.

 

Well, I put the old fuel injectors in after putting new o rings on them and viola, runs great. The wires I bought actually have the cylinder number on them and i triple checked that the wires were in the right place so it wasn't that. When i went to put the old injectors back on and tried to bleed the fuel pressure off the line there wasnt any. I'm wondering if a few injectors were stuck open, causing the super rich exhaust smell that I was getting as well as the lack of fuel line pressure when disassembling. Would improper fuel air ratio cause misfires like that?

 

I don’t know, but would think so.

Remanned injectors are 50 or so on eBay. I went that route when doing my Head Gaskets.

 

Yeah I did my head gaskets when I bought the rover. Got $2000 off the price when I bought it. Unfortunatley I didn't do anything with the injectors back then. I was getting a lean running condition code and the brake cleaner told me it was a bad o ring on one of my fuel injectors. The lean code it gone but I have a wicked knock going on. While I have you guys, does anyone recognize this noise? Is it perhaps the infamous friction fit liner slippage?

 

Did you do the valve stem seals when you did the head gaskets? I had to redo my Hg’s because mine started severely leaking even though they passed a vacuum test.

 

Ouch, that's a fun job to do twice. I'm pretty sure that the head shop did them when I dropped them off. How did you find out they were leaking?

 

Oil was coming out of the side of the HG. Was hard to believe, but it was.

 

Lol. I have a wicked oil leak myself and I'm not entirely sure where its coming from. Literally everything is coated in oil. The entire oil pan, steering rods, entire front axle, you name it and its covered in oil. I took about 5 cans of brake cleaner to the undercarriage and added some ultraviolet dye to the oil and as far as I could tell it looks like it may be coming from the rear main seal and making it's way out the peep hole between the block and bell housing. I'm just not sure why within a day everything is coated with oil again. I've owned 3 discoverys in my life and I've never had one that went more than 6 months without leaking oil. If there is no oil under it, there is no oil in it.

 

Look around the underside of the HG’s. I could see it coming out, and it was causing misfires.
