Alright for those who want to chime in on my difficulties pleeez do. At the time my trans was redone the trans man asked me if I had misfiring: no. He said well it is and thought maybe I had a coil pack problem but I wanted it back so I took it home without him checking the problem out a week ago.
I have had an over all loss of power that is esp bad when trying to excellerate from 35 or 40. depress the pedal and no response. hold it there and in 5 to 8 seconds the engine begins to kick in and excellerate then it will throw my back aggainst the seat and behave like nothings wrong. esp in the higher rpm.
My opinion has been all along that it is a fuel air mixture - fuel delivery issue.
I replaced the fuel filter. nothing
I cleaned the MAF. nothing.
I dumped seafoam into the tank. ..ran great 5 miles then prob back.
Ipulled the codes: P0300 random misfiring and o2 sensor bank 1 sensor 1.
I replaced the o2 sensor on both forward banks. nothing.
I replaced the plugs. nothing.
I have been thinking bad gas all along and am down to a quarter tank. I filled a new tank the night beforre the trans died. so index of suspicion up.
What could the trans man have done if it is something his actions caused???
I pulled the EGR valvelast night. I plugged the plenum inlet and laid the EGR valve on the top of the engine and turned the engine on with the harness connected to the EGR valve. The engine was pretty much up to temp. So I revved the engine and watched the EGR valve pinion . . It did not move at all- ever. Did not open. So with my backyards mechanics mind I figured just maybe that valve is not responding. So I got a new one and now here I am with a broken bolt and still misfiring engine.
If this is still misfiring after I whip this EGR prob and get new gas then the only thing I can think of is to buy a coil pack and play musical chairs with it in the hopes that it will finally hit on a cylinder that had a bad coil pack. but wouldn't I have thrown a P0301 -0306 code? by now???
Oh and I checked the fuel pressure with a tester on the rail. With the key on it pops up to 38. After starting it drop to a steady 31-34 psi.
My idle is fine. when it does get going it is smooth. ???? any thoughts.???....maybe its the Throttle position sensor.... Gee I will buy one those next.
