I have a 2003 Acura CL type s 6 speed. It won’t go passed 3,000 at all. A few codes came up. They were all cylinders 1-6 a random misfire code and both O2 Sensor codes. I replaced everything. I really need some help because I’m not trying to keep dumping money into her as much as I love her I’m moving next week and my girl tripping on me spending to much money on this car lmao PLEASE YOU GUYS ARE ALL I HAVE RIGHT NOW.

Any other DTC's ? Like for the crank sensors?


When you 'replaced everything'? (o2 sensors, I presume), did you disconnect the battery?

Im sorry what do DTC’s mean & no smh how long do I let it sit?

Random misfires can be plugs and coils. Have your replaced your plugs? I'd pull some and look at their condition.

I did and they were burnt so I replaced them with NGK sparks. & I changed the coils a week ago.

Have you investigated a potentially clogged cat? it would cause all the symptoms listed.

DTC=Diagnostic Trouble Codes

Either pull the #13 clock fuse and reinsert ,after a minute or so on the passenger side dash fuse box, or disconnect the neg bat. cable and let it sit for 3-5minutes. Turn all electrical devices off in the car a/c, radio, lights etc. Start the car, don't touch the gas pedal, let it idle for at least three radiator fan cycles for the idle relearn process. Take for a drive and PRAY it solves your problem; otherwise, if there are no other specific DTC's, to help point you in the right direction, a visit to the dealer my be the next step.

thoiboi

what coils did you replace them with?

2ndBreakingNecks

I’m guessing that’s the case for the codes that was given. I might just straight pipe it. For the time being.

Do you have access to a heat/thermal gun (Harbor Freight has them cheap) and see if the exhaust temp pre-cat and post-cat are widely off. They should be approximately the same temp. If pre-cat is much much hotter than post-cat, see if you have good exhaust pressure out of the tail pipe. Cheap way of figuring it out without buying a new cat. However, cats for these cars are pretty cheap (RockAuto)... As long as you don't have to comply with California emissions or something crazy like that.
