Not trying to thread jack but Ive having the same issues, this just started happening to me today. I washed my engine bay on Tuesday, and everything was working fine, I covered my fusebox and pod air filter. I took my car out today (Friday) and everything seemed fine as I went to the shop to get an wheel alignment done. The tech finished aligning my wheels and took my car for a little cruise to test out his work. As he passed the shop I heard the car struggling on the road, and thought "oh god, this guy cant drive a standard." He comes back and asks me if Ive been having issues with it, I told him no. He says it wasnt revving up and it was stalling, he had to keep the pedal pinned to make it back to the shop. I reset my ecu, and left the shop, and of course it started happening to me.
When I get it up to about 2500RPM it starts to chatter and bog out, but not all the time. I checked for codes, and supposedly Im "55". If I keep shifting at 2500RPM while its doing this and get into 4th or 5th gear it will usually go away for a bit and let me rev past 3-4K RPM. I can then down shift into a lower gear and still rev past 3-4K, but it still has the occasional bog out and lurch.
Ive tried playing with my TPS trying to find a sweet spot to no avail. I set it all the way clockwise when it was doing this to me after I left the shop, and the Idle fluctuated between 1500 and 2000 RPM (figured it would be higher all the way over), I didnt have my multimeter so its hard to say where it was. I made it home because it was mostly freeway and the car doesnt seem to run poorly when maintaining a good speed in a high gear.
I checked for codes again, still none. I got my multimeter out and reset my TPS to .48V(750RPM) and went for a drive. It runs fine for a while, but at some point when sitting at a light it just stalls and becomes hard to start. When I finally do get it started the idle is high (1500RPM) and sometimes it even starts jumping around quickly between 1-2K. I turned on my lights when it was doing this quick rev jumping and it leveled out the idle at a crazy high 1900RPM. Took it for a drive and it still was bogging/chattering/lurching. I checked the voltage at my fuel pump when it was doing this and its around 13.55V the whole time. A lot of the time the idle is steady (but stalls), but in this one instance that I caught on the first video it went berserk.
INFO - New fuel filter, fuel pump, clean resoldered MAF, fairly new plugs, good fuel pressure (Tomei reg + gauge).
Could my TPS cause my vehicle to run like this? Or have I been visited by a electrical ghost?
Im posting videos as they upload, any help would be appreciated.
