What up guys, Got an engine problem.
So sure i have been trying to blow the ol' 2.9 for like years as an excuse to do a 5.0. but i got like 3 months till i get to put it in and am having a problem.
so hear it is and i am hoping its a quick fix. the frog runs fine til it warms up. then when the engine is under load it starts giving me this wierd sort of exhaust leak sound from what i guess to be the passenger side of the engine. and i loose almost all my horse power. like i have to go up hills in 2nd, at 20 miles an hour. it doesnt affect it as much at lower rpm's around 1000, and gets worse as i aproch 2.5 and then it wont go any higher. stops at 2.5 grand
so here is some enviromental factors. i have a snorkle, the heater is bypassed the two hoses are just looping around. thats al i can think of, dont think the would be the problem but i am just throing that out.
so if anyone has any ideas thanks.

if it is the 2.9L pull codes and go from there, if you have no codes showing I would say coolent temp sensor.

that is a possibility, also check the timing...

Timing is too slow. You are most likely hearing the popping through the intake. An intake valve is slightly open as the engine is firing. Mine just had a very similar problem. I re-adjusted the timing and everything went back to normal.
The exaust would also have contributed to it

Can't think of anything witty, intelligent, or cool to say...guess I'm just stupid.
ok, checked the timing , its suposed to be 10, it was around 20, then i found you have to unplug this little thing called a spout, so did that, and it read around 6. i dont know if thats way good or way bad. but then i found out that apparently you cant adjust timing on the 2.9 TFI??? i tore the whole distributer apart and you cant adjust it??? anyone have any input?

You are suppose to unplug that piece and then set your timing. I don't think the 6*btdc would give you that much probelms. They are timiable though. You may have jumped the timing chain if it has a lot of miles and you have been beating on it.

yea, the more i look into it the more it looks like timing is not the issue, seems the coolent temperature sensor causes a similar problem, by feeding too much fuel to the motor, but i dont think thats it cuz everone says it smokes when i does that. its crazy too, cuz alot of people aparently have this same problem but noone has any answers.

ok, first off you can set the timing with a light. lossen the bolt at the base of the distributor and turn it untill it reads right on the crank.
second, the timing is chain driven on the 2.9L. it is gear driven on the 2.8L.
if you timing is 4 degrees off you can have issues...how bad I guess we will see, but it will run bad. fix that first then you rule it out.
