My 1985 Fiero is hard to start and when it starts it idols but when I put it in gear it goes dead ?? I put in a new Idol control valve and a new Throttle position sensor, I did notice when I put the TPS on the lever on the side that looks like it should adjust the lever on the carb was causing the car to idol at full throttle so I had to remove the lever from the TPS and then it would idol correctly. But it goes dead when I put it in gear ?????

Have you checked for vacuum leaks ?

Spray a small amount of starting fluid around all suspected areas and if it revs up that's where you leak is.

If you replaced the timing belt and the car has been doing this, it is possible you are 1 tooth out with the timing belt.

coulb be a vacuum leak at the intake, any codes set( eng light on?) follow them if so

my ford winstar vav stalls when you put it in drive will idol all day just find

You are not getting fuel. EIther bad fuel pump or plugged fuel filter. No fuel pressure and it starts for a second with starting fluid, then there is no fuel being pumped to fuel lines.

it could be your starter going bad

the idle air control valve is stuck,or there is a vacuum leak.check the vacuum lines,the throttle cable is not sticking and the idle control valve which is on the side of the throttle body and the throttle position sensor.check all the plugs on these for a good connection.

Have same car, same problems, easy solutions.

Getting into gear has been improved by putting in neutral with engine running to warm up fluid. The Fiero has very little room in the pedal area. I'm shifting a lot better with smaller shoes.

The problem with starting may well be related to the same issue. There is a neutral safety starting switch. If you're not pressing hard enough on the clutch - starter won't run. According to the Fierostore.com stock clutch pedals tend to bend. They sell a stronger replacement.

My Fiero has been starting just fine the last few days. The last time it didn't I was wearing boots.

I've almost always been able to get it to start using a booster battery, but Walmart's tester indicates that the battery and charging system are fine. It recommends tightening connections. I did this, but still had problems for a while.

did you properly adjust the throttle position sensor? it is not just a pull and replace part, it does have an adjustment. This could be your problem!

to me this sounds like your ignition timeing is off because of the hard start and the no power when accelerating. I would definently check the timing out on it
hope this helps you out
