Why is my 3.2 so slow??

Mike, great shot, I will wait until tomorrow to do it. Have to get up at 4am. But thanks again that will be first on the list. I know some say a leak down but one was done less then a year ago and all was fine but will do one step at a time.

Well gents, problem solved thanks to you all. Upon checking really close today the throttle plate was not opening all the way, yesterday I thought about a quarter of an inch, it was almost a Half an inch. Ajusted the ball nut as per Mikes photo, mine was extremly rusted, had to soak a while in wd 40 and then it took 5 complete turns. Proceeded to the full throttle switch it was getting 5 volts but no continuity unless I smashed on the gas pedal, ajusted that and went for a ride. Different car by far!!! Thanks again Mike and all.

Good that is what it was. Like those easy fixes.
Help anytime I can, as with everybody here.

Congrats! It always feels good when the car goes faster after working on it

Great news!

That's great news - Steve Wong and I talked about this in length a few years ago - he estimates about 30-40 are not engaging the WOT switch - like you - the car feels sluggish.

One of the first things I did with my car - it makes a huge difference!

You will need a continuity tester or multimeter to check this. The switch should activate by 2/3 to 3/4 throttle opening. Also, if your throttle linkage is not pulling the throttle open all the way, you will need to adjust it as Jeremy says, usually under the car. Have someone press on the gas pedal, while you check to see how far it opens. You would be surprised how many owners do not check and remedy this. The difference is around 10-15 hp. I've recently been getting dyno sheets from 3.2 owners with wacked up air fuel ratio data, attributed to a non-activating switch, which tell me even astute owners are not checking this basic function.

Here is the WOT switch:



Runfile 003 shows what happens when you go full throttle without the WOT switch activating. You can see it goes very rich above 5000, and the resultant HP loss. Run files 006 and 011 shows what happens when the switch activates.

Nice to hear you found some power on the table, you might have more just waiting for you to find. If the wife starts screaming next time your out on a drive your almost there.

All the best
