Hi Everyone. I'm playing around with my 74 2.0 liter trying to get it to run a little better. It "bucks" occasionally so I was looking at the TPS yesterday. I couldn't get the TPS off to open it up,I think there may be locktite on the screws and I was afraid to really reef on it!! But I did try the 20 click test,but I heard no clicks. None!! What does this mean? Is the TPS not functioning at all? What would that do for driveability? I don't have much frame of reference as this is my first 914, but the car does seem to exhibit the ususal TPS problems. That is...it bucks, and the acceleration is sluggish.
Any and all comments really appreciated!!! Cheers Mike |

One of the things that I found was that the wrong way to do things was to adjust things and then replace the harness with a Bowlsby harness. I should have done that first. I had things running as best they could and then replaced the stock harness with a Bowlsby harness only to find that all that fiddling to get things set perfectly was only compensating for the ills of the old harness and weak components. I had to restart all the fiddling around when I put the new harness in. Should have started there.
40 years of corrosion and broken wires will screw up everything you are trying to do. Those Keyser/Bowlsby boys make a harness that is well worth the money... |

(IMG:style_emoticons/default/agree.gif) I bought Jeff's harness first then replaced everything, but might as well take a look at the tps circuit board, replacing it is only $35 and if that fixes what ail you and your satisfied then great!! If not then you may want took take a look at the wiring and fix or replace before you hunt down and pay for potential causes, bucking is common issue tps especially at low constant speeds.. Ie: what he is saying is that if you phone calls keep getting dropped or poor connection buying a series of new cell phones won't fix the problem you need a new carrier.. |
