Welcome...
The
very 1st and most important thing you should do is buy a instant feedback gauge.
Without instantaneous feedback it is hard to know what works and what doesn't.
Information can be found here.
ScanGauge - Trip Computer + Digitial Gauges + ScanTools
UltraGauge OBDII Scan tool & Information Center
Both of these are easy to install. They just plug into the cars OBDII port.
Without it your shooting in the dark...

Edit.
Will the ScanGaugeII work on my vehicle that was purchased outside of the US and Canada?
The ScanGauge requires the vehicle to be either OBDII or EOBD compatible. In the US and Canada, cars and light trucks were required to be OBDII compatible starting in 1996. In Europe, EOBD was phased in between 2002 and 2004. Other parts of the world have required one of them starting in various years.
Many vehicles made and/or sold outside the US and Canada had one of the protocols before they were required in that country. This was to allow sales to other countries and because they knew they would eventually be required to meet the requirements and designed it in when they redesigned a particular model.
There is no comprehensive list of when particular vehicles began using OBDII or EOBD outside the US and Canada.

UltraGauge is compatible with most* 1996 and newer foreign and domestic vehicles sold in the United States. While OBD II compliance was federally mandated in 1996, some vehicle makes and models were compliant as early as 1994. Compliance is indicated on the vehicle's emissions decal located in the engine compartment. Below are examples of emission decals.

Will UltraGauge work with my vehicle?
The following must be true:
1. "OBDII Certified" is printed on the vehicle's emission decal or in the vehicle's manual
2. Your vehicle is not listed on our compatibility exceptions list: Compatibility Exceptions
International Customers
Please confirm that your vehicle is OBDII certified. UltraGauge is only compatible with vehicles which are OBDII certified. While OBDII compliance was mandated in the USA in 1996, this is not true internationally. Most countries eventually did adopt the OBDII standard. However, vehicles sold prior to OBDII adoption may or may not be OBDII compliant. For example, Australia did not adopt the OBDII until 2006. However, many pre-2006 vehicles are compliant, many are not.

If your car is not compatible. You will have to use a MPGuino like Metro suggested.
