Got new motor put in a 1991 Toyota Camry it idles fine but when you give it gas it dies what could cause that and how do you fix it?

Answer 1

From most likely to least:

Ignition problem (worn plugs, old wires, cracked distrib. rotor, worn distrib cap) - replace bad parts. You should really replace all of the above and the valve cover gasket also. Use only spark plugs of OE type, construsction, configuration, gap, and heat range. My personal preferance is for Denso when available and NGK otherwise.

Low fuel pressure or contaminated fuel. Add fuel or replace filter, pump, or regulator depending on which is the cause.

Bad throttle position sensor.

Replace as needed.

alot of times dick heads do motor swaps on cars and charge people way more than it should be and they dont change over the most simple cheap things you could think of that is probly the same motor but out of a junk yard. The best thing you can do is buy spark plugs, and wires,cap, and roter, oil filter, put new oil in it, and cheack all your fuses, and it will make a differance! if not than it mite have some electric probloms if it does work that motor is gona be high maintinince any way,down the line your gona have to change the water pump, headgaskit, valve covergaskit a whole bunch of stuff you sholdint have to do and its a shame but i bet money that dude keept your old motor and gave you a crapy one out off a junk yard that he probly said had 60,000miles or somthin but it was really like 260,000miles happins all the time
