So I changed my spark plugs 2 days ago and I disconnected the throttle body sensor while doing the change (I plugged it back in after the process) and when I put the new spark plugs in (NGK spark plugs) I lost more than like 75% of my power. It felt very weak and it didn’t feel like the same car at all, I’ve tried searching it up but couldn’t find anything. When I put the NGK ones in I didn’t check the gap or torque them down. So I went and bought new spark plugs this time the recommended denso ones from the dealership instead of getting NGK’s again. I gapped them and torqued them down to the correct spec (18 foot pound ). I did the reset TPS process (The video tutorial said I need 12.9v in my battery when I did the TPS process but I only had 12.2v I didn’t want to go out and buy a new one so I still did the process). When I tested the car out it gained power and it wasn’t accelerating by itself anymore but I still lacked power I couldn’t spin any wheels ( I could usually spin wheels with just 65% throttle ). Can someone please help me out I’m really lost. Feel free to ask questions and I’ll respond.

 

disconnect your battery for about an hour then hook it back up. that will help resett the ECU
