Look for a vaccum leak in the intake manifold most likely there is either a dry rotted rubber hose that has a hole in it or a hose came off generally it will be somewhere near the firewall.

The idle air control is sticking or the throttle position sensor is out.

Hi,My 89' Reliant stalls when slowing down to a stop sign or parking lot.Could the cause be the fuelpump or distributer pickup?


Possibly a fuel issue, but have the pressure checked before condemning the pump. Is the gas filter good? And the air filter?

It could be an idling issue-idle too low. Check if can be raised, or if idle control motor or valve needs service. Idle should be around 750 rpm, in drive gear, maybe a bit lower, not below 650 rpm, though.

Why does my 89 justy die when i slow down?


It could be any number of things. The MAP sensor is bad, a severe vacuum leak, the fuel filter is plugged, it needs a tune-up like new plugs & wires etc., the fuel pump is weak or leaking if its a manual one. If the car runs rough at idle have a vacuum test done also, while the car is running at night, open the hood and see if the plug wires are arcing as you will see what looks like small lightning sparks around the wires. The worst case scenario is the piston rings are shot causing poor compression. A repair manual is usually available at the local auto parts store, or shopping center like Wal-Mart and Meijer.
I wish you the best of luck.

After getting my 95 GMC Sierra 1500 5.7L V-8 back from a failed emissions test I let their mechanic fix it( or pass smog) However, now when the truck is in park the rpm's are at 1200 about 300...


I had an 89 Chevy Silverado with a high idle problem, A lot of money later and a lawsuit against a repair shop that said they fixed it and they didn't caused early engine failure and they wind up paying for a new engine. Long story short, I found out the main cause was I had to replace the throttle body gasket because it was bad causing more air intake and the on board computer tried to compensate for the air by adding more fuel therefore, high idle. I hope this helped.

I have an 89 Honda Accord lx and it idles too low


The idle speed for my 88 accord lx is 700-850 rpm for standard idle speed. The stalling is a seperate issue. When were plugs, wires, air/gas filters and distributor last checked? How long has engine been running for when you stall? Is the temprature gauge high? Any lights coming on when stall occurs? I am not a mechanic, but a DYI'er. These are common questions I am always asked when troubleshooting my Honda. :)

89 Accord LXI Idle problems


It's fuel infected and it has a vacuum leak, most likely a PCV valve that is stuck open, I've seen a few now. Replace the PCV valve 1st, if that doesn't fix it, start looking for a hose that has come off.

Idle RPM


the idle on most firebirds are set from the factory and are not adjustable but you could look on the sticker on the bottom side of the hood or above the radiator. the emission control or the drive belt routing sticker should have it on there. hope this helps you... god bless
