What size socket do I need for the caliper bolts? I obviously don't have the right one.
Little help?
I have found some cars with similar problems on the discussion board but would appreciate some new input,
I have the Service(check) Engine Soon light illumninated.
My jimmy started to lose acceleration as I was driving from Harrisburg to Pittsburgh , at around 60 MPH going up inclines it appeared not to accelerate even when floored. I eventually had to pull over going up a steep incline as the car started to physically jerk (RPMS), i think that this uncoincidentally coincided after my releasing and flooring the gas,,, "experimenting" (I'm not dumb, the jerking came after I releasd and floored the gas). After I pulled over I eventually got going by feathering the gas to slowly accelerate and stay at about 60 all the way to pittsburgh ,, when going up inclines i did not try to keep speed i routinely fell down to 45 mph, not trying to push the engine, I smelled what I thought to be like some sort of burning smell occasionally but then it would quickly dissappear.
I have read on the discussion board that catalytic converter or feul pump might be problem, I just replaced my feul pump around 2.5 months ago so i dont think it would be that.
Any other suggestions ? I would greatly appreciate it...
thanks all
p.s. Also when i was going at very slow speed: 2-5 mph and my wheel was turned extreme right or left the jimmy was reallllly straining , any suggestions for that , or relation to previous problem ?
Diagnostic Code: P0421 -> Catalyst Efficiency Below Threshold
Apparently the Feul Injectors for "Bank 1" are clogged, this is what I was told, I was given some cleaning fluid to put in my tank and it should clear it up , it makes sense when they explained it to me, was not getting gas in those cylinders when trying to accelerate ....
HOWEVER,
I still have the problem with the turn with the wheel turned far to the right or left, Apparently when in two wheel drive it is fine, however in 4 HI it is messed up, i did not try in 4 LO, it appears to be ok in 4 WD AUTO, but I remember the only time I ever used 4 WD AUTO it was good for an hour or so and then I remember a similar type of jerking that I am now getting with the 4 HI , AutoZone was not sure what it might be they only speculated that it might be a vaccuum leak in the actuator controlling the switch to 4wd ,,,,
Summary:
1) Acceleration Fixed, Problem was Clogged Feul Injectors
2) Lurching, even when pushing hard on gas when in 4 HI with wheels turned extreme left or right
Any idea what could be causing the trouble in the 4 HI would be greatly appreciated,
Thanks again for the help
Please help if you have worked with the factory radio, I would rather be prepare before taken the dash apart.
Thanks,
Thanks!
Has anybody had to deal with this one before? What does it mean? What I need to do about it? How badly does it need to be fixed?
I love this forum - almost all the other weird problems I've had to deal with on this car have already been addressed here - e.g., the constant turn signal clicking, ridiculous transmission overflow tube, etc.
P1810 TFP Valve Position Switch Circuit (GM)
Mine started after I had to chargw the battery up when it went dead, I have heat ever since and I have the same symptoms.
Thanks

It turned out to be the ignition switch. Thank God I got a good mechanic that saw it before, the dealership could not fix it.
