My 2001 Suzuki Vitara has a lot of engine power but when I hold my gas pedal to the floor it does not go past 50 mph. It doesn't seem to want to shift unless I let up on the gas pedal for a sec then it goes into overdrive but take a while to go any faster than 50 mph. Where do I start?

Shift lock solenoid could be the problem , or brake light switch ,or shift lock relay . Your vehicle has a safety system known as shift lock or interlock , what ever suzuki calls it . It will not allow the shifter to move from park to any gear unless drivers foot is pushing the brake pedal . You can view wiring diagram here at http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size .Then under system click on transmission / transaxle . Then under subsystem click on transmission controls , hit the search button , the click first blue link . At the top of the diagram an on the right side you will see shift lock relay ,Then down near the bottom on the left side you will see the shift lock solenoid . You could test these with a volt meter ,do you have an know how to do that ? Where is your shifter ? on the floor or on the steering column ? You will need to disassemble parts of your vehicle to get at these parts .So check the relay first , do you have a owners manual ? Should tell you the location in there .
low power is caused by many things.
1: dragging brakes or very low tire pressure (dangerous)
2: slipping transmission, called Flare or will not up shift. to 4th gear and overdrive TC clutch lock.
3: weak engine. there are 4 engines used USA. so what engine , if engine is weak.
G16, J20, H25, H27?
we can not guess engines.ever or country.
When you "floor the gas pedal" the computor goes into a bypass mode (emergency mode). This honestly sounds a lot like a problem I ran into a while back on a Dodge truck. Problem was a cracked intake manifold (plastic). Short version: vacuum leak.
No check engine light? Take it to a parts store that will do a free code check (engine light). There's a lot of things that could cause your problem, from some minor vacuum leak (cracked vacuum hose etc.) to a throttle position sensor.
its probably the kickdown cable look under the hood its the cable that runs next to the throttle cable see if there's alot of slack or if its too tight and not letting it release all the way.
This is a electric heat boost for demisting in winter months, turn fan on to full, heater lever to full and air controll to full. Be warned uses lots of battery power
My car did (past tense) the same thing. The service engine light is flashing until you let off the gas because raw fuel is being dumped into the catalytic converter. The transmission won't shift because the converter is plugged. When you push the pedal to the floor the transmission computer holds the transmission in gear. Meanwhile the engine computer is raising the rpms. It will seem like a transmission problem but it is more likely a plugged catalytic converter. I had converter changed. The engine has A LOT more power, great acceleration and the transmission shifts perfectly.
