96 tercel Problems STILL

[cattlick]

Ok Ive taken a break and getting ready to start back on the Ol reliable Toyota Tercel. Right now the car will run great for about 15-30 seconds after starting. After that it seems that any position on the gas pedal more than 25 percent will find it stuttering, fluttering and loosing power.
Here is what I have tried. New Plugs and wires, new bug and rotor, new distributor, new battery, new fuel filter, few fuel pump. I have tripple checked the timing and we are getting it dead on. New Airfilter, Changed out tps, iat with not change.

ANyone have any help I would greatlyl appreciate it. I need this little ol car to get around when the hot rods are just sucking up the gas.
Thanks

Try another map sensor. I'd grab one from salvage, also grab a spare ecu at salvage to try.

ps Chris, swap in a 4efte and you can sell the 'hot rod'. The Tercel can get 30+mpg and run 11's in the quarter. Hard to beat that combo.

I was considering weather or not to post up my similar problem. but firstly, when did this first start happening to you? for me it was after my distributor rotor dry rotted into a million pieces. new parts and its all kinda fubar still ...getting any codes? I'm getting 12,14,24,52.

@Tercel GTS which one is the map sensor? I'd like to try one of those as well because finding an ecu for my car on this island is...not on my list of options at the moment, and I've done everything except test the map sensor and test a spare ecu (which I don't have)

The map sensor is on the firewall normally behind the intake manifold. It has one vacuum line and an electrical connector with 3 wires.
