What Do I Have Going On Now ??

I'm still working on getting my $1k driver on the road.

I've got the idle dialed in. ( Was too rich )

I figured out with Brad's info. That the Throttle Position Switch is tits up. Unplugged it and it runs smooth.

But some thing else is goofy. The car starts sputtering at 3000 rpms ( 1/3 throttle), with little or no power. ( This is with the TPS unplugged ). But it was acting the same way last night with the TPS plugged in.

After rereading the Timing Tech Article. The hoses should be disconnected and plugged. They weren't when I checked it.
So we know timing is wrong.

But its load specific. Sitting in neutral, it revs to 5k without a beat or miss. ( TPS unlpugged ). Go out and drive it. Anything past 1/3 throttle and it goes to sputtering.

Thoughts ???

The kids did wash it yesterday, so I'll open the Distributor Cap and check for moisture.

Hey there Cary,
I had the same problem with my 1.7. I changed the TPS. It helped a little but not completely. Then I did the CHT. Again, it helped a little but...
I pulled the dizzy, cleaned & checked the FI points... then noticed a slight wobble in the dizzy shaft. Put it back in and sometimes it ran strong & sometimes it got the sputter back.
I still had the points & condensor set up so I went to the Pertronics electronic ignition. That seemed to take care of the sputtering at 3k. It may have been just the points but it also could'a been a combo of changing it all.
bruce

ps. I have your tape of the autocross. Can I send it to the Main St. address?

Yes, that would be great. How much do I owe you ?

I've been reading the posts you had. Sounds about the same thing. I think the more we drive it. The more things are loosening up.
I know the TPS is shot. Had a real bad flat spot at 2800. I'm pulling it off this am to take a look at it. I ordered a new one last night.
CHT is withing the #'s.
The dizzy is my next project. Sounds like the FI trigger points might be
it. Dwell is right 49.5.
But how do you get the b***h out. The VA is right over the clamp nut.

Out to tinker this am. But I have to reset the ride height on the Carrera for our biggest AX, Monday. At one of the car dealerships on one of Missoula main drags. Lots of folks.

On the 1.7 we'll get her figured out. TTYL.

To get to the nut so's ya can extract the dizzy you'll need to loosen the adjustment nut and turn the VA outta the way then it's visible. Here's a pic from Pelican showing the adustment nut
http://www.pelicanparts.com/techarticles/914_timing/914_timing_pic2_big.JPG. It's a hard pic to read. Mark the placement of the dizzy before loosening and twisting it outta the way so's you can get it back in the right position. That way it'll at least start & you can re-time it.
Don't worry 'bout the cost of shipping. I think it's only a couple bucks & the tape is a used one from work!
Good luck
bruce

Thanks for the shipping.

I'm waiting for the TPS. I'm pretty certain thats it. My drivabilty problems are strictly related to the pressure on the throttle.
The car will roll up the 5k as long as I don't mash down on the throttle. After about 1/3 throttle the engine goes to mush.

Should be here by the weekend.

Just FYI, the link you posted is not valid. Good Luck Cary.

The auto-URL recognizer included the period he put at the end of the sentence. Just remove that final dot and it should work.

To avoid this problem in the future, put a space in between URLs and any punctuation. E.g., " http://www.pelicanparts.com/techarticles/914_timing/914_timing_pic2_big.JPG ."
