Anyone in Miami,FL area got an OBDI and/or a Multimeter??
 

Hello Board,
Does anyone live in the Miami,FL area on this board and can help me run a diagnostic on my car?? The shops in my area want to charge me big$$ to diagnose my cars condition. I think that the previous owner of my car must have tampered with my fuel/air mixture. The car idles relitavely smoothly(sometimes),and it smokes(blackish,running rich?) and the exhaust smells heavily of gasoline. I feel that the car must be guzzling extra fuel to cover up othr problems.I have a feeling that my car is in fact running rich(or lean??), but the mechanics want to charge me an arm and a leg. If it is possible,can anyone help me out with readjusting the mixture and diagnosing any other problems??

c'mon guys, I really need some help here.

Do not take me wrong, but coming back just 1/2 later asking again does not help.
People like to help around here, but no one likes to be pressured.
DO A SEARCH, probably you would have found all the info you needed in the 1/2 wait for a reply. There has to be ton of posts in the archives with your same problem.

Here is my 0.02 cents:

That same condition was caused by an O2 sensor going bad in my car. It could be something else in yours.

Get yourself a multimeter with duty cycle reading. I believe they are on sale right now at Sears. There is a post with a picture and the info.
I will be gald to help you with details on how to diagnose the car if you do not find it already posted.

OBD is used on '96 and up. Yours are all < and you don't mention which of your 2 cars is failing.

You own 2 MBs and you don't want to pay a hr. or two labor for a diagnosis by someone who understands??

I think it's an 87 300E with an 89 300E engine and modified to look like a 95 E320.

That car is neither OBD I nor OBD II compliant and a few posts ago someone mentioned that Sears has on sale for $20 a multimeter with duty cycle function. Exactly what you need to check the EHA function.
