Ok someone please help me with this. I need this car back up and going.

Here is the dilemma:

I start the car in the morning, let it warm up. I take off and drive to work no problems not even a stumble. I get to work (17 mins away) and when I pull into the parking spot the car idles LOW and shakes and then stalls. Same thing happens after I come out of work and get home.

Checked fuel pressure and it is 39-40 at idle and stays. Pressure stays as I shut the car off also. Just replaced the wires and plugs. Had the ICM spacer mod (shoeboxs washer idea) but had to pull the heads to change out the valve stem seals and did not put the washeers back in afterwards. Only other thing that is out of the norm is I havthe O2s unplugged (went bad).

I don't have a scanner and don't want to pay 30 bux to have codes pulled. I have a SES light but I am assuming it is the O2s because it doesn't come on right away.

PLEASE HELP AS THIS IS MY DD!!!!!!!!!!!!

Also its a 94 formula.

 

There are 3 reasons you aren't getting an answer. 1) You won't pay for a scan so we assume you won't buy a scanner either. Without certain basic information from a scanner, none of us can get the information needed to help you (including you getting the information to help yourself).

2) Your assuming the cause of the SES light. If you wish to assume, fix what you think is the cause and see if the light goes out. If not then you know it has another cause.

3) You haven't provided enough information to help. For example you mentioned that pulling into the parking spot causes it to stumble. In my mind I think it's because you are no longer holding the throttle (and thus the RPMs) up. Therefore it should have the same stumbling problem when ever you come to a stop light. However you didn't mention it. Is the parking spot at an angle so that when you park the fuel runs away from the pump possibly uncovering a whole in the pickup tube between the pump and the hard lines??????? See what I mean. NEI.
