Hard Start Problem

Replaced spark plugs and still had the same issue so I changed the computer and that did the trick

Hello, in winter my corolla has troublem reaching 50 km/h to do that I have to press hard on the accelerator. In summer I hardly reavh 40km/h on hill. It didn't do that before an year. All this happened sice I went on a very steep hill with hard acceleration.
I tried start the car on Neutral engine starts smmoth and nice. What is the problem.

Car can't not started after already started? No matter how long. It wont start up the second start in the same day

I have a 93 toy. Corolla and I have replaced the wires cap rotor and spark plugs and changed the oil and filter. And I am going crazy car runs rough, there isnt no ticking except the injectors and there isnt no smoke what so ever. I was told heads and others tell me they not sure what the problem is. SOOO my last person told my change the distibutor because of contact issues. I am at wits end here, because this car is slow to start but takes off when it hits second gear and does awsome. Does anyone have any ideas here? Also there is a somewhat gas smell from there exhaust.

Yes I t does and its a exhuast issue but what would cause the running hard issue with the motor while it is in drive or any other gear for that matter. Distribitor?

Had a engine light come on, took it to a repair shop could not fix. Took it to a Toyota dealer service center they had it for 4 days and could not fix the problem either. The car is a 1992 Toyota Corolla DX sedan with 200500 miles, when the car is cold on first starting up it runs rough for about 15 seconds and then it run great. After start up tried to give it some gas and has no power until 15 seconds warm up then it runs great and has power after I step on the gas. Replaced the coolant temp sensor as the code read it was bad, but it is still rough when the engine is cold, until it warms up after a few seconds?

Removed cold start injector and clean a bit, hit the injector where it slides open reinstalled, removed the air cleaner and started the car and it run good. No rough starting step on gas had power. But still check engine light is on?

What is obd 1?

Dear sir, Thanks for the wonderful service your doing. I am from Philippines and thus know very little about the cars out here. I bought my Toyota corolla 1991 model year 1995 second hand and I had the regular oil changes done every 15000km and cleaning of aircon every 6 months.
Now my problem is I did not use my car for almost a month due to engine problem. The last time I use my car, the car is dragging and the engine automatically shut off. Every time happen this thing, I will continue to start again the engine ( hard start) before you start the engine, after a miles the problem comes again.
I already change the Spark plug and cleaning the carburator system but the problem stil there. Other mechanics advice me to change the engine than to repair the engine, because I will spend to much money for the repair than to buy a new second hand engine.
Advanced thanks for helping me, This is my first car I bought when I married and until now I'm using this car for my family.

i can drive maybe 3 miles run into a store and when I come back out I have trouble starting the car, it turn's over but doesn't catch. Could it be the heating sensor?
