Default What can cause retardation of timing......

the car has no power really, well it's there but you can feel that it is being retarded, only accelerated in 2nd gear 10 mph over 1/8 of a mile or so. It is symetric meaning not only one cyclender but the whole engine. ALso it only does it under load.....any help is much appreciated!!

Default FIXED, here is what happen.......

I went to loook at a car for some one else today and the CEL came on, checked it when i got home and it was the for the TPS, 2121. So i was like oh well maybe i didn't set the sensor. Checked it and it moved half the width of the screws that hold it down, for those who don't know these screws, they are as wide as a smaller key ring that has a 1 inch diameter. Well i put i on and the car hesitates like crazy reatarded timing all sorts of stuff, but no CEL. NOw it started just after playing with the TB, the very sever part of it all. So im like WTF, throw on a STB that i have and i also do the telephone cord mod to the penulum. Do them both and the car is AMAZING, better than ever before. SO it must be the TPS. Swap the TPS' for my clay TB and everything is perfect.

Dumb logic though is that if the sensor was not right from the start, which was last fall or earlier, then it would have thrown a CEL, but since it didn't till now then it must have died. Also may put the bored out MAF back in and see how that does.


OK time for a shower, food, and another graduation party....YESSSS!!!!!!!!
