Question about 1982 Alfa Romeo Spider

1 Answer

79 spider veloce 2000 start

It sat for 25 years and only has 14k miles. recently dumped/changed all fluids, all filters.
New fuel pump. Started and ran. Stalled 3-4 times after 15 minutes when driven. Looked under- saw catalytic glowing bright xmas red ! So mix coming out was super rich... Let it cool overnite. Next day and since; it fires up for 2 seconds- stalls, fires up- stalls, once it fired and ran for 1 minute and stalled, and on and on. Engine is getting fuel for this initial ignition and then dies. Exhaust must still be rich with fuel. Checked fuel lines to Spica pump and its flowing good into and out of it. All air/vac hoses connected. going nuts. whats next? thx

    more? i wish i knew what to tell. By the way, your comment was cutoff after "antifreeze also..."

  • eran Feb 08, 2009

    i thought the cat was plugged but when it does run for 20-30 seconds once in a while and i got my hand on the exhaust pipe, i feel a real nice, free flow. so i keep thinking about fuel flow, maybe injectors, maybe some control switch somewhere??

  • eran Feb 08, 2009

    thinking about getting rid of the cat converter alltogether. Although the car was born in NJ it is now in florida and where no one will ever look to see if it meets pollution regs. If the cat is gone it may just make it happier and allow better echaust flow regardless. So next week its the chop saw to the exhaust pipe...

    Say another thing I have seen several cats plugged and still flowing exhaust out.. so keep that in mind .you might drop the exhaust and run it for a bit and make sure . you might run some chemtool through the fuel system to clean it up also.. just another thought.. which you might have already done.. setting sure hurts one doesnt it. its worse than driving it all the time I believe .. brakes go also seals and fuel problems .. thanks Jerry

    strange you say the cat is bright red ? and it set for 14 years ? is it possable you have a clogged exhaust system ? just wondered if maybe some mice got in there and made their home or something like that ?? just a thought.. Jerry

Hello Eran,

Normally I would jump at the opportunity to point
to the catalytic convertor as your trouble...
(or rusty muffler (has nothing to do with mileage)).

But so hot ... so fast leads me to think it is
being over fueled... If you can beg, borrow or buy a simple mechanics stethoscope you can listen to the injectors clicking.

Pick out anyone that sounds different and clear it by spraying
BERRYMANS Chemtool (see below)...
((handle it carefully... can take the PAINT off (pronto))).

Once you have eliminated the black smoke
(stuck injectors) the engine should be running
smooth enough to identify what other issues...

I would try to then OPEN the exhaust system above the catalytic converter to see if the engine runs better. Obviously you cannot drive (or even heat up the engine in that condition... but it might
tell you if the converter is STILL FAILING.

USE lots of liquid WRENCH (good 6 point wrenches)
and take your time...

Take it to a muffler shop for analysis
(just know your prices BEFORE you go)...

Hope this helps.

Sixteen year old car with only 40K miles must not be driven often, or sat for some time. I would suspect fuel system issue, such as bad pump, clogged filter, bad regulator or faulty injectors. Start by testing fuel pressure.

Powerglide transmission

Ouch...sat too long and the transmission fluid is probably like molasses... Try pulling the tranny pan, dump the fluid, clean the pan and change the filter and refill with DEXRON fluid. Also add some SeaFoam transmission additive. Start it up and when engine is at operating tempuature, SLOWLY put it in all gears. Shift back and forth, back and forth (with your foot on the brake !). Hopefully the new fluid and the SeaFoam will clean up the internal parts. If and whne the car is driveable, drive about 100 miles and then dump the fluid, filter and refill. Add another can of SeaFoam. Hope this helps....
Good Luck

2001 dodge ram1500 /accelerates slow even w/peddle to the floor

How many miles on that rig? The 4.7 motor is a great motor.

Sounds like a fuel starvation issue. Might also be a trans issue. Does the trans seem to be shifting properly?? Could it be starting in 2nd gear which is the "limp mode" for Chrysler trannies?

'92 Chevy pu V8 will not start spray in starting fluid and it starts then starts rest of day. sits over night have to go back to spraying with starting fluid. What is the problem? How do I fix it? '92...

With your Clarifications I suggest having the Fuel Pump Pressure Tested as one other gentleman suggested that it is most likely bleeding down overnight. Another possibility would be the Fuel Filter being clogged. The factory recommendation is to change fuel filters every 30,000 miles. Many people do not even know a Fuel Filter exists on their vehicles. Some years back they were near or in the carb. Weak Ignition would be the last thing to look into as the vehicle runs somewhat normally once started and running for a while. Modern vehicles have Electric Fuel Pumps inside the Fuel Tank. This is somewhat expensive to replace but necessary maintenance after many many miles. Good Luck!

Stalls out about every 10 miles or so,let sit bout 5min,restarts

have you changed the plugs and leads, if you don't know the last time it was started there is a few things you need to take into account, engine oil and spark plugs fuel filter even the fuel in the tank empty and replace, coil and the points ( if upgraded there is no coil and points as been converted) you would also need to clean out the carburetor as old fuel drying can block or limit fuel entering the engine. change air filter. even standing an engine for a year or 2 these parts can degrade as they have not been used. also change the water and flush the system and refill with coolant/antifreeze.
