test your intake air temp sensor and engine temp sensor http://www.shbox.com/1/4th_gen_tech2.html#ect
the 94 is obd1 but is different from the 93 or 95 you can not flash codes like a 93 but does use a obd1 scanner unfortunatly it has to be compatable.
test your evap system, test fuel pressure regulator and fuel pressure. how old are your 02 sensors, have your injectors ever been cleaned and flow tested? check the maf to see if its dirty. check all plugins for bent or damged pins.

i want to remove the egr function as well as the smog/air system. are there issues when doing that? ive heard conflicting info. im going to do the coolant bypass soon and want to do the other stuff at the same time.
so how to i figure out what code reader will scan a 94? do generic ones normally not scan a 94 car?

10 mpg of course means that you are consuming more fuel
either your tires are way underinflated (Obama told us to check our air pressure)
your brakes are dragging
you do all driving within LA or NYNY
someone is stealing your gas
your gas station's meters aren't calibrated and you're only getting 1/2 the fuel for which you are being charged
your fuel tank is leaking
your tranny is slipping so badly that you are turning 4500 rpm going 10 mph
or you are running very rich
if it's the latter, then chances are an O2 sensor isn't behaving
you can find a wealth of data by capturing a data log. Then, if you want it tuned, especially to delete EGR or even VATS, after you capture the log, send it to Solomon at www.lt1pcmtuning.com and he will tune your car as well as help you interpret the data

please allow me to perform a CBA for you (cost-benefit-analysis)
buy the cable from aldl and also tuning service from solomon for a whopping $130 total
you claim to only get 10mpg and since I'm confident that you aren't using cheap gas, but are using premium, it's about $3.20 per gallon
let's say you drive 250 miles per week which is 25 gallons x $3.20 = $80 per week fuel
if you get a tune, and that's all that is needed then you should see around 18mpg at 250 miles per week is approx 14 gallons of fuel x $3.20 per gallon = $44.80 per week or $35.20 savings per week.
You achieve payback in less than 1 month even if you paid 2 months finance charge on a credit card for the $130 purchase
then let's explore the annual savings and assume month # 1 pays for the cable and tune, then month 2-12 is incremental savings or 48 weeks x $35.20 = $1,689.60 additional savings just in year one
so, to be brutally honest with you, do you really want to **** around over a cable or do those cold hard numbers slap you in the face and tell you what you should be doing???????????
Sorry if this seems harsh but when you look at the above, the correct method is obvious.

Its not a daily driver. I have maybe driven 100 times since may when I bought it. I already spent hours reading stuff on that site and have software.ive put a tranny in it, the thing is costing me, and why buy a cable if I dont need to? You like payn for stuff you can make? And ive seen guys soler in serial connector on plenty of cars.basically you dont know and they arent telling or no one would buy a cable,lol

so lets say i order the cable from aldlcable and i cant scan my car with a innova brand scanner, whats to say i dont have a problem that will not allow the cable to work either?
if i can get some more clarification as far as why the innova brand cant connect to my ecu then ill order the cable , but i hate to order when moneys tight and find out i have a greater issue like a bad ecu, and there was a hypertech piggy back on this car so i wouldnt be surprised if my ecu has issues
and are some cables not compatible with certain software? is the and advantage using a serial cable instead of a usb? like say serial with usb adapter. my laptop has no serial its too new

that's a big thumbs up
for me, the easiest was to spend $70 and use Solomon lt1pcmtuning.com
not only do you get his experience but it's good to have another informed opinion. And then, the tune is customized for your vehicle.
he'll tell you in a heartbeat if it looks like you may have other issues such as O2's, exhaust leak, other sensors
