I followed Rob's lead today with the same result. Now it's smooth notchy. For those of you that haven't seen it all apart-  I also removed the front part of the console to get a better view of the throttle cable. I think this is 16yrs worth of grime.  | ||

Rob, Now try a little spray white grease which is little more permanent lube after the PB breaks up the corrosion. | ||

Well, after driving it to work today. It's a smooth notchy, which is better than a rough notcy, so half better, but I would like it to be much more smoother. I'll start looking into other things when I have time. | ||

It should last for sometime, but figure every 3 months give it a shot of PB. Remember the only thing that last forever is Herpes (sorry). | ||

After driving today I finally decided to take a closer look. I removed the driver side mats and the plate that goes around the throttle pedal. You wouldn't believe all the stuff down in there. Mostly carpet threads that had wrapped in and around each and every way. I picked out what I could with my hands and then PB Blasted the heck out of it. Immediately I could tell the difference by pressing with my hand. I haven't driven it yet, but by how it felt with my hand it's going to be great. Will PB also lubricate it long term? I'm worried that once it evaporates that it will go back to being rough, although there should be less dirt down there now. Thanks for the help, it worked perfect and only took 5-10 minutes. | ||

I have the same problem with my F40, but only when the car has been running for a while and the engine is very hot. I have tried all the lubrication points but no change. I have been told by Ferrari UK that 355s have the same problem. Any ideas? | ||

If it doesn't respond quickly to lubrication, then most likely the cable is frayed & it's new cable time. BTW, search the archives, I think someone suggested bicycle cable as a longer lasting replacement. | ||

Damn Rob, I started having the same problem 2 weeks ago when I went to pick up BobD at the mechanics. Kind of embarassing, stalling your car at an intersection with another F owner riding shotgun. It's getting worse, and it's making it harder and harder to drive smoothly. Maybe we need to hook up some afternoon and do a compare and fix. | ||

I've lubed my cable a couple of times with a graphite based lock lubricant from TrueValue. The graphite is suspended in a petroleum solvent. Both times, I just took the cable off of the throttle body & out of the bracket that holds it to the fwd cam cover. This lets the cable stick straight up. Pull the cable out of the jacket until there's enough of a gap to drop the lube onto the cable. It flows nicely down into the jacket. Someone suggested that after dropping as much into the cable as it will hold, to hold the end of the cable so an air gun will blow into the jacket, thus forcing the lube the length of the cable. Should work, but havent needed to so far. I wouldn't use it in a lock tho, IMHO straight graphite is the best thing for locks. The | ||

Rob, I don't know about the 328 but I was able to isolate a problem on my 308 by pulling the cotter pin on the throttle body (??) and removing the cable. I was then able to check the spring action of the "butterfly" on the throttle body (or whatever it's called) as well as the cable feel. My problem was OE during reassembly I had routed the cable over the return spring. | ||

Had the same problem with a 308QV a few years ago. Greasing the cable and linkages helped for a while but once I had the cable replaced, it was frayed and binding, I never had the problem again. | ||

I'm noticing a little of this on my 88TR. Has anyone had this problem with the TR? If so, can you tell me specifically where to lube? Thanks. | ||

Rob, I had the same problem, my mechanic had to grease/lubricate both the throttle body mechanism (easy) and the pedal linkage (harder to access). Once done, all was smooth sailing... | ||

It's not inherent in the 328. Mine's smooth. Can't help on the fix, though... | ||

Rob, Grease linkage behind pedal, try PB Blaster. Down here in Fla with all the salt and humidty I have to do mine every couple of months. Paul | ||

Under your car between the two front wheels is a plate covering the throttle assembly. Jack the car an d look to see if it is bent up. If it is, Remove it and hammer it flat. Mine did the same thing. Once I fixed the plate is was smooth | ||

When trying to be sensitive with the gas pedal in stop and go traffic for example. The first part of the pedal travel is really notchy. It doesn't feel smooth like most cars. You go in notches from no gas to woo horse to wooooo horse. You get past a point and it's smooth, but notchy when feathering it. Something inherent with Ferraris or the 328 and I have to live with? Throttle cable needs greasing? Something with the pedal linkage? Thanks, rob |
