First off car is bone stock, except for exhaust.
89 Firebird Formula, w/tpi, and 160,000miles, shift kit

Well the car was running fine, i drove it 400 hundred miles, and then it sat for 2 weeks, tried to start is and it will not barely idle, and when i put it in gear it just stalls. It was running well then it sat now its dead.

I have spark, fuel, my compression was around 100(did not test all cylinders), no engine codes had it scanned,

so now i am lost just got the car 4-5 months ago, and not sure what to troubleshoot first, changed the O2, and mass air,

the book said allot about the EGR valve but I can't see it making that big of a problem. the car will barely run?

Please help anyone THanks start

check for moisture in the distributor......check ignition module......pick-up coil.....all the connections also......fuel pressure....to list a few......

 

I had the same problem, try checking the Neutral Safety switch...

 

I would pop off the throttle body (15 minutes) and hit it with carb cleaner. Pull off the IAC, and see how much carbon is at the tip of the pintle. Be careful when cleaning it. Reset the pintle, by pushing in with your thumb. The computer will reset it once it is reinstalled and you've driven it a bit. You may be surprised on how much carbon is in there, especially if you have leaky valve guides. If that doesnt work, make sure your within your timing specs.

 

Well going to try that all today, one last question, my mechinac friend says that the EGR valve could cause that, is that true is there a way to test the EGR system?

btw thanks for all the help!!

one more thing mt timing is advanced 17degs

 

I just had to replace the EGR on my car, yes ur car would not run with a broken one, mine didnt at least. I tried driving it but it just stalled out
Im not sure if thats the cause but it was on my car

 

yes, an egr would certainly cause this. To me it sounds like it's dumping too much exhaust into the engine.

 

I live in detroit michigan and we don't have emmissons here, Is there a way to run the car by dissconeting the EGR all together because i really need my car right now. Just some way to rig it for the time being.

Thanks far all your support guys

you can pull the egr valve off and make a block off plate for over the hole, your check engine light will come on though

 

pull the vac line off the egr valve and plug it, the tap on the side of the valve,l see if it runs any better, if not , pull the valve off and see if it is stuck open
