hey guys, my new '90 ranger 2.9 i just picked up has no power whats so ever. on the highway up a slight hill floored in 5th gear at 60ish i loose speed and i barely hold it in fourth. on start up it seems to pop and chock for a few seconds until it settles out and idles fine koeo fuel pressure is solid at 38 for well over a minuet, i checked the timing and its at about 10* btc but i now realize that the SPOUT was definitely plugged in, but at idle, not adjusting it, shouldn't it not really matter..? i havent pulled the codes as of yet. any help would be great guys

Recheck the timing with the spout removed. Even at idle it advances the timing significantly.

okay i will and ill post results

Yes, check timing with SPOUT disabled

How many miles on the engine?
Might be worth while to do a compression test, compression is directly related to power.

Not sure if the '90 non-calif. 2.9l will have an EGR system, these actually add power if working correctly, they allow more spark advance without knocking/pinging on regular gas, but can rob power if not working correctly.

well dash sayd 8000 so 108,000? 208,000 maybr, though it looks too nice of shape to be 208

am i supossed to pull the wires off of the icm? or if there a harness somewhere further down the line?

nesralyrrej · Feb 11, 2015

wait, its that little grey block, isnt it?

RonD · Feb 11, 2015

No, there is a two wire connector with a slide in contact, you pull out this contact to disable SPOUT connection.
Picture in #5 post here: http://www.therangerstation.com/forums/showthread.php?t=132369

And #2 post here: http://www.fordrangerforum.com/2-9-liter-tech/93749-1988-ranger-timing.html

The connector in #5 is shown laying on the TFI module, that is just for the picture, it is on that wiring harness but not necessarily at that location, the slide in plastic connector can be black or grey, and usually the wires are yellow.

EDIT:
Opps, you posted while I was typing, yes, it is that grey block

nesralyrrej · Feb 11, 2015

haha yeah i figured as much, if the timing isnt it, any other ideas?

RonD · Feb 11, 2015

If it was at 10 BTDC with SPOUT working then part of your problem will be the timing.

Get that set and then see what improvement there is.

Advance your timing to 12-15*.

bobbywalter · Feb 11, 2015

what was the timing at?

what does the vacuum gauge do?

what do the spark plugs loo like?

the timing was at like 8*

at idle im at like 12 lbs of vacuum

i have also noticed fairly excessive fuel usage, a half tank (down from full) got me about 110 miles.

im beginning to think its a clogged cat, thoughts?
