While checking out my stumbling problem on my V6, I decided to start checking out sensors and stuff.
I've got a new cap/rotor, plugs/wires, ignition module and coil. I haven't changed the pick up yet.
So, things I have found.
The ECM is throwing no codes,
IAC very difficult to move in and out. Cleaned the ports with EFI cleaner, got the IAC moving a bit better after fooling with for a couple of min. I just read a post by the ogre on testing the IAC, will do that tomorrow.
checked the resistence on the TPS. Ohms were nice and steady on the meter untill about part throttle, it went O.L. on my fluke but started giving a reading again at about 3/4 throttle. I assume this means a bad TPS. Its not throwing a code though, how can this be. If I accelerate slowly & smoothly, its fine. If I nail the gas, it stumbles and then accelerates.
Its not throwing a code, so I am a little puzzled. Anyone else found this on a TPS?
