Sup everyone.. So i recently bought a 1G Acura CL 3.0 on craigslist. When I first test drove it it was driving super smooth you can tell this guy that owned it took good care of it. I hooked up my scan tool and had no check engine lights and nothing had been rest recently. So I purchased it for $1,000 it has 202,000 miles on it but i just need it for my a to b car. I stop by autozone and buy some new spark plug wires,spark plugs(it had copper plugs but i upgraded to platinum) and stuff for an oil change. Everything was installed accordingly but then a couple days after my tune up I get a Random misfire code and all cylinder misfire codes. So i figure the upgraded spark plug might be drawing to much power over the old copper ones so i replaced the distributor and ignition coil and still the same issue..I tried the spark plug wire pull test and it seems like my back three cylinders don't make the engine start bogging down. Do you think i should switch back to copper plugs?

 

Only use OEM spark plugs and wires

 

Any links to where to buy oem plugs

 

I got it all figured out now!! I had a look at the timing and my belt had jumped 2 teeth on the back cylinders so I changed the timing belt and water pump.
Now its all good!!!
