Any ways 3 months into it get told were having twins 2 days latter boss tells me there laying off ppl and i'm on the block. so income go's down, babies on the way and $$$ goes to the red the Biuld is OFF. so i'm back to the Stock Del Sol. 95 Si Automatic. i still have the (list Below)

5 speed swap parts -1 clutch set
n1 cat back Installed
Look-a-Like-a-cat stright pipe cat replacer Installed
4-2-1 Header Installed
aem Short Ram intake w/k&n Installed
and the full MSD Ignition setup (A6, cap, wires, rotor, blaster ss coil) Installed
with a installed autometer Wideband guage 10.0:1~20.0:1 readout


Tuneing Q's Below

So when i started this all i put the Short ram, exhaust system, the Msd setup and the Wideband in the stock car. at idle and cruasing i get 14.6~14.9 A/F foot off the gas coasting 20.0 (lean as Hell) foot into it 12.3~12.9 WOT 10.0 (rich as all hell) the Auto Ecu Is Stock and i was getting about 23~25 Mpg.

about a month ago it all changed
at idle and cruasing i get 14.6~14.9 A/F
and any thing elase is 20.0 it will go to 13.6 for a sec when i put my foot down but right back to 20.0.

i didn't do any thing to the motor or the electrical system of the car. and now i seem to be getting 32 MPG and the car has Alot More power then befor. also there are NO CEL's any infor would be nice.

What size & impedance injectors are you running ?
Are you running a resistor box ?

the car is mostly stock when i got the car it was not running. I found that the fuel tank was full of rust so i put in a new fuel tank walbro 255 fuel pump new filter new Stock injectors and purged the fuel lines. car ran fine but was only getting 19 Mpg added seafoam (2 cans) to a full tank of gas. added 1/2 can to the oil (used 10w30 for this) and 1/2 can feed to the intake. after the tank of fuel i installed a new O2 sensor and fuel filer (just to make sure i got all the rust out of the system and i didn't find any) stared getting 23~25MPg. after looking online i found Most ppl selling the same car used where getting 24Mpg so i called it good. At this time i installed the 4-2-1 header,cat N1 catback, aem coldair (i has as of yesterday removed the lower half and made it a short ram) aem fuel rail, the MSD setup and NGK iridium plugs. all runnung on the Stock ECU for the Automatic (yes the car is still an automatic) i have all the sensors for the motor as i still have the D16Z6 i was going to biuld up. added AFR and Fuel Pressure gauge with stock FR i was gettin 32PSI w/vac 42wo/Vac set the AFR to 34Psi w/VAC 44wo/Vac after reading that 2Psi gave better spay pattern with out hurting the Stock Injectors after all that i was Getting 27Mpg and getting A/F reading of 14.7:1 at idel and Crusing with 10.0:1 at WOT and 20.0:1 with my foot off the throttle. all was fine then one day when i took off fro work it just stoped reading the same 14.7:1 idel and cruse but 20.0:1 at WOT and with my foot off the thottle. i didn't do anything to the cat at that time. i warrentied the O2 for the ECU and still the same readings got Autometer to send me a new O2 for the gauge and still the sameA/F readingsplug in a friends Autometer Gauge and still the same readings. So i think it's eather the ECM or some other sensor But i have No idea where to look. i have a chiped ECM for a %speed but i'm Not sure if this will work for testing.

so anyone have any ideas could it be timing?
