I have a 1989 chevy Beretta i just bought it a few days ago and itruns great in park but when you put it in drive it starts bogging down a little then eventually dies but will start rite back up...Also stall when coming to a stop. I was told it could be the coil packs but i dont want to change them if that isnt the problem Oh yeah i changed plugs and wires too.

i isn't your ignition,it's the tcc lockup on the transmission that is causing the trouble,the torque converter is remaining locked instead of releasing which stalls the engine every time you put it in gear,you need to see a transmission professional or the dealer for repairs,if the car has a warranty then get it fixed under the warranty.

Well gm it wasnt the tcc but while i was looking for the tcc wires i found a square plastic box about 2 inches square and about a half an inch thick also has 3-4 wires coming out of it one runs to the firewall the rest are cut I dont know if that is the problem..And what that piece does or what it is...And i also noticed that the stalling happens in park sometimes too...hmmm

now that is something you haven't mentioned before that it stalls in park,the possibilies there could be a faulty iac valve,crank position sensor.plug wires,plugs,dirty plugged fuel filter,bad fuel pump.

yeah Good wrench i had just picked the car up and didnt realize it stalled in park...but it runs smooth for a few seconds then starts bucking and dies but then it starts rite back up same in drive when im doing over 10 mi an hour its ok then when i go to slow down it bucks and dies. i just dont get it i change plugs and wires im wondering if it could be the coil but i dont know much about coils.and thank you gw for taking time to help me out i went without a car for a while now i got my beretta and i like it just not the way it runs...The body is the only good thing about it rite now till i get it running rite.

no the tps isn't causing this but i do want you to have the fuel pump pressure tested,they buck/pitch and stall if the pump isn't able to keep up with demand,check the reading against book specs,anything lower than specs means a bad pump or clogged filter.i was thinking about this last night,a bad pump can seem like a bad crank sensor.

will using a scanner tell me if the fuel pump is bad?I have a small budget to work with...If i had the money i would just bring it to a shop and let them deal with it. but my buddy is gonna let me use his scanner tomorrow and i hope it at least tells me whats wrong.and once again thank you for your time.I just cant wait to find out what is wrong.Then i will know what i need to spend to fixer up and bring her back to life.I have so many things i want to do to it.

you do not need anything as sophisticated as a scanner to test the fuel pump,you need a direct reading pressure gauge type tester that you simply connect to the end of the fuel filter or line from the pump,turn on the key and you have 5-10 seconds to read the gauge before the pump shuts off.you can use a scanner if you have a check engine light on which means there are trouble codes stored in the memory and the scanner will retrieve them.otherwise a diagnostic run should be done by a certified technician or at the dealer.

ok good wrench just bought a cheap scanner today..Yes the check engine light comes on every time i use the car.So im going to try the scanner out tomorrow and my freind is going to help me check fuel pump..I also picked up a fuel filter and pcv valve i dont know if there is anything wrong with the ones in it but at the very least i will know when they were replaced last.

Ok good wrench used scanner ..replaced tps,o2 sensor and pcv valve. the scanner threw a code 13 so i replaced those parts and diconnected the battery to clear codes.Now it throws no code but it lopes while idle.And when i go from drive to park it idles up for a few seconds then drops down and then idles up again it does this for 5-10 minutes than smooths out.sometimes when it idles down it just cuts out.now from what ive heard it isnt the coils which is what i thought at first I am going crazy ...someone mentioned the ECM what do you think.

more likely the crank position sensor or idle air control valve,try pulling the idleair control valve and cleaning both the valve and the housing they get sooty/gummy and stop working. let me know what you find out.

Disconnecting the battery causes the ECM to lose the learned idle position for the IAC (Idle Air Control valve). You now have to relearn the IAC or it can greatly affect the idle quality and do a lot of the things you are experiencing.

The best and easiest way to do this is with a scanner that has that function. If a scanner is not available then if I recall correctly, letting it idle, IN DRIVE, for 10 minutes will accomplish the same thing. This method doesn't always work so great as I recall.

I've got an 89 Beretta as well that does the same thing. I replaced the air filter to start with, which drastically reduced the problem, but it still does it. When the RPM's drop below about 1000, it tries to stall out and lurch foward. Not really sure what the cause is... but any help would be appriciated.......

look on the transmission where the fluid cooling lines are,see that square 4 wire plug? disconnect it and see if the trouble goes away,if it does the trouble is the tcc solenoid in the tranny keeping the lockup converter engaged when it should be released

89 Beretta dies
10-30-03 09:02 AM - Post#299947    
    In response to good.wrench

When my beretta runs it runs just fine... idles and revs fine, but sometimes it just dies no sputtering... just dies... and once it dies it wont start. Then other times it just wont start. Originally thought that it was related to temp, right now I can even give it all night and it wont start. When it doesnt start, there is no spark. From reading all other posts... think maybe will change Crank Sensor? then see what happens.

Any ideas?
Tom

check for spark a second time,if you have no spark then next thing to check is the wiring from the crank position sensor to the ignition control module,those wires get bare and sometimes touch grounding everything out,if those are ok then the crank position sensor would be next,one morevthing,when it won't start does it crank over?

Yes the engine does crank over. Will check again for spark and before I change the crank position sensor I will check the wiring for shorts.

Thanks
