Question about 1988 Toyota Pickup
Truck has 160K miles on motor. When I start it cold (even in the summer) it lopes like it's drowning with to much fuel. I can smell the unburned gas in the exhaust has black smoke, my mileage bites hard and it tries to stall (sometime does). But after it warms up a bit (the temp needle with a small space in between the bottom temp line) I can turn the truck off wait a minute or two and start it back up and it runs smooth as ice (one would never know there was no muffler on it) but I did constrict the end of the pipe a bit for back pressure. The plugs, fuel filter, air filter, oil, all new and I typically go between 55 and 60 mph going anywhere (taking a easy).
Any ideas would be great
Could be a number of different things.Fuel pressure relief valve not working,injector pulse too long,Is the air box lid securely fastened and air cleaner clean.Are there no leaks between the air box and throttle body(intake tube).Have you checked oxy sensor.air flow meter may be also possible.Try squeezing the flexible fuel hose enough to allow the engine to run and see if the engine reacts better if it does you have excessive fuel pressure.

i assume its a 4 cyl?? will this car ever overheat if just sitting idle? when it begins to overheat, hows the heat in the cab? sounds like maybe the radiator is partially clogged or restricted somehow. i would change the radiator cap and make sure the overflow is set to proper level. (incl. radiator level) i wouldnt jump to headgasket just yet, they are pretty durable from what ive seen

in your carburetor there is a priming passage. look in there with the air cleaner out and pump the butterfly it should squirt gas. if it doesn't then you need to open the top part of the carb and clean the hole with a hair clip. if this is not the problem it will be the choke but I'm 70 percent that this is the problem.

your problem is in your throttle sensor that controls the idle it is located right behind your intake and it has two screws that mounts it i am almost positive that this is where your problem is comig from
