R Walling Posted April 30, 2020 Share Posted April 30, 2020 After spending a lot of time diagnosing the electronic and fuel system, I was told that it may be stale gas that is causing the problem. I drained the 4 or 5 year old gas and put in 5 gal. of fresh gas. IT IS NOW RUNNING!!!😀😁👍 It took a few minutes to settle down and idle smoothly but the smoke and horrible smell is now gone. I was able to bring the rpm up to 3500 rpm for the first tome and it kept running! I an still getting a code 35 and the idle is 200 rpm too high but it does run. 1 Link to comment Share on other sites More sharing options...
Lebowski Posted April 30, 2020 Share Posted April 30, 2020 (edited) If you're a Fiero guy you're going to love what other Fiero owners do in this video. Have some tissues ready at the end of it....

Guest Posted May 3, 2020 Share Posted May 3, 2020 Well today I have good news and bad news. The bad, I drove it around my yard and it did what Fieros do best, it caught fire. The good news, only burnt the spark plug wires before I got it out. (I always carry my trusty fire extingusher) That was the last straw, I am now going to install a 4.9 Caddy engine in it after perusing the Fiero site.

JFranklin Posted May 3, 2020 Share Posted May 3, 2020 If that was the V-6 I don't think you would have had a fire. It was the 4 cyl. models that caused the demise of Fiero. My V-6 never caught fire! Link to comment Share on other sites More sharing options...
padgett Posted May 3, 2020 Share Posted May 3, 2020 a) 84 were all Iron Duke b) Was nothing wrong with the engine. GM decided it only needed a three quart oiling system. Americans often get 2 qt low and ignore warning lights.. Rod exits on firewall side and last quart dumps on catalyst (hot) and starter (lostsa amps). GM recall did four things: - new page in owner's manual - remarked dipstick - longer oil filter. - shield over catalyst and starter all revised for '85 Link to comment Share on other sites More sharing options...
