Come and take it
Searched and searched without any answers. Here I have my 94 cruiser. Once warmed up the engine will run nice and smooth, but about every thirty seconds or so it gets really rough like it isn’t firing on all cylinders. Idles rough for approximately 10 seconds and then goes back to smooth. Does it consistent at idle.
If I drive it off it stumbles hard like a plug wire isn’t hooked up and then after about 3500rpm it smooths out. Once the gear shifts and the rpm’s drop, the roughness comes back. Was getting code 28 and 21 previously so I replaced both sensors today with Toyota units. Cleared code and the same issue is here after driving for 10 miles. I replaced every vacuum hose about 2 years ago, Intake hose is new checked it all anyways and cannot find the culprit. Any other ideas or suggestions?
I will try and post a video next.
