Merry Xmas & Happy New Year to everyone. Please someone help me. Yesterday I turn on the car because I was going to take it to a paint job. But when I runned it, it felt (in spanish we said: ahogado; the literal translation to that is drowned, but I don't know if the terminology is used literal), like the gasoline is not doing it right. The engine only staid started if i keep the revs over 2,000 or more. It turn off on idle speed. I tried to go thru a hill and in first gear it almost didn't make it. The gas pedal was down to the floor, and in the hill it was almost dead. The car is smoking a little bit, thing that it never made before, until yesterday.
Everything came after I changed the TB to a 60 mm. In that process the TPS break and I haven't replace it because I read here that somebody says that it wasn't necesary.
Do I need a new TPS?
Is the TPS making the malfunction?
What else could it be?


P.D.:I am really sorry if I can't explain me well, but in technical things the translation of english and spanish is not always literal so I don't know exactly how to explain in english. And I'm no mechanic, just a student, so please be patience with me.

The TPS shouldn't affect it so much that it floods... It sounds like it's running too rich, or too lean.

What color is the exhaust smoke?
-Black sooted smoke means it's running too rich


Start with pulling the spark plugs. look at the tips & see if they are wet, black, or tan.

Wet= flooded
Black=too rich
Tan=too lean

yes nismo the smoke is a little black and ir smell like burn gasoline

NismoPick

It's gotta be runnin too rich.

Check all the sensor connections to make sure nothing got knocked loose. Especially the head temp sensor on the right side of the head.

Was anything else touched when doing the 60mm tb? Like the AFM, or idle adjustment screw?

what you mean with sensor connections?; What sensor? I just know the TPS; about the head temp sensor, where is that?; what you mean by the head?; I just move the AFM a little bit to take the tb out easier, but anything else; and about the idle adjustment screw, I don't think that i touched it.
What should I do or change?
Should I get a new TPS anyway?

NismoPick

head = cylinder head on top of the engine block.

the head temp sensor & AFM are the main sensors that will cause a fuel problem. I would also advise in getting the TPS sensor back on.

hey nismo you're great!!!
last question (by now): Ok, this is what I am going to do:
1. check the spark plugs. If anyone is wet, black or tan, should I replace it?
2. check all the connections
3. get the new tps
4. check the AFM. How do I know if it is Ok?
5. how do I know if the idle adjustment screw is ok?

If the motor ran fine before the T/B mod, I'd seriously check the AFM electrical connections and then for a major vacuum leak. This would be anywhere in between the AFM and T/B and any other lines that should be attached. Does the new T/B have the same number vacuum connections as the old one? Maybe there's one that needs to be capped off. Are any vacuum lines cracked or broken?

jfairladyz

Yeah I'm going to go with canyoncarver on this one. I'm thinking a vacuum hose got left unplugged or got knocked loose somewhere. Also, when you moved the AFM, it may have pulled a wire or the entire connector loose. But I'd go with vacuum leak first.

EatmyDust

if you are refering to the performanc 60mm tb in motor sport, have to use a difrent idle ajdustment screw the ariginal one isn't the right one. that is what it sounds like to me.

I would like to say thanks to everyone. The problem was in the hose that goes out of the fuel pressure regulator; it had a crack, and it causes a failure.

NismoPick

Sheesh! Good thing it didn't blow. You didn't notice a heavy "fuel" smell?

RodMoyes

I think He's talking about the vacuum line.... (Not fuel line).
