As mentioned before, clean the MAF Sensor and IAC Valve. If that doesn't help, check the vacuum lines.
Where were they trying to read the computer from. Under the dashboard or engine bay?

dont use the obd2 code scanners. use jumper wire method. Ill post a pic for you to follow. its very simple.

mayosailor27 · April 10th, 2011, 02:56 AM

try the moethod on the lowe left of the pic. 2 inch piece of wire, turn ze key count ze flashes. very easy. Report back after you get the flashes.

BTW USE THE connection on the passenger side under the hood. Its next to the accumulator--black thing that is cylindrical. May have a cover on it it may not just depends on PO's usage

mayosailor27 · April 10th, 2011, 03:16 AM

Yeah that's some funny stuff right there, can't use the dashboard one, but yet it's there. haha

So now I'm curious, what's the jumper for?

mayosailor27 · April 10th, 2011, 03:56 AM

To connect to circuit for the computer to spit out codes--idk. lol. thats what i figured. EVEN if there isnt a CEL on the computer will still store the codes that came on for a 0.0000000000000000001 of a second.

Interesting.
I have no problems scanning/reading mine.

Ps. If you have your heater/air condition turned on it will through a code out when scanning.

mayosailor27 · April 10th, 2011, 04:09 AM

No problems reading it with what? the obd2 scanner?

I had no problem using a scanner for reading codes...
or are you saying the jumper is so you can use a OB2 Scanner?

fogged306 · April 10th, 2011, 02:08 PM

The jumper is for the self test. When you jump the sig return to the self test wire, the computer goes into self test mode and will flash the check engine light in a sequence of flashes for the codes stored. OBD2 didn't start until 96 even though some 95 and maybe even some 94 models have the OBD2 plug.

Oh snap! I didn't even know you can self test, that's cool.
