I recently backdated the exhaust on my 75 to 2l heat exchangers & a triad muffler.
Previous to the change the starter would spin normally and the car would start normally. Now after the backdate the starter is very sluggish (with a fully charged battery) even though it is sluggish the car will fire and run when it occasionally catches. At first thought I thought maybe there could be blockage in the exhaust but after it ran I am not so sure. I thought I heard new valve train noise on the passenger side, so just in case I pulled the passenger side spark plugs and test started it with no effect, I'll try the driver side plugs tomorrow. With the backdate I blocked the EGR, and removed the EGR lead from the old muffler. Any thoughts? |

errant detachment of that pesky ground strap from transaxle to body?

hmmm, that makes sense, I don't remember seeing a ground strap when I was working under there. I'll check it out.
I really didn't mess with anything else, aside from the EGR stuff it was a straight forward swap. |

what an astute group, first (and second) answers were spot on.
While doing the swap I noticed the rear trans mounts had been installed incorrectly so I dropped the trans just enough to put them on right, It must have been too much and busted the strap (IMG:style_emoticons/default/headbang.gif) . thanks again!

(IMG:style_emoticons/default/smilie_pokal.gif) Kenny as second place winner how about a hot start relay, slightly used of course.
I'll even "freshin" it up with some gold paint to look like a fer real trophy (IMG:style_emoticons/default/smilie_pokal.gif) seriously though I really appreciate the lead, I went for the first real 914 ride in well over a year today because of the help |
