<font face="Comic Sans MS">What year is it? Which engine does it have? EFI or carbuerated? How exactly is it running bad, i.e. what's it doing?</font>

Re: runing bad

&lt;font face="Comic Sans MS"&gt;Best initial guess would be EGR valve sticking open. Are there any codes being stored in the computer? You can take the connector and jumper two pins and it should flash the check engine light in patterns to list codes. To test the EGR you have to push up on the diaphragm inside it and make sure it moves somewhat smoothly and returns to it's normal position. You might have to take it off and clean the carbon out of it. Then just general stuff, vacuum lines, and all that junk.&lt;/font&gt;
