98 ranger 3.0 has no get up and go at all
My 98 ranger 3.0 is an 4 speed automatic. But if you were standing beside it when I took off you would swear it was a standard. It sounds and feels like your riding the clutch when you take off. You have to stand on the accelerator with both feet to get it up to 70 no power at all

Welcome to the forum
Could be a few things I assume the CEL(Check engine light) works? Comes on with key on and then goes off when cranking engine over and it starts And the CEL stays off when driving so no Trouble codes With no codes that will mean it could be restricted air flow in or clogged exhaust system out Possibly a failing torque converter, but OD OFF light on the dash should flash now and then Check the air cleaner and the tube that comes into the air cleaner box from rad support, the cold air intake tube, make sure there are no "mouse houses" Clogged exhaust is hard to test, you can do it with a vacuum gauge on the intake Or pull out the 2 O2 sensors near the engine and go for a drive |

Yes, Cat converter and muffler are part of the exhaust system, so either one could break apart inside and restrict exhaust flow
Cold engine Open the hood and look on passenger side of the engine for the exhaust manifold on that side, toward the rear it will have a pipe bolted to it, about 4"- 6" farther down you will see the Passenger side upstream O2 sensor, designation Bank 1 sensor 1 In the drivers side you will see the same setup, designation Bank 2 Sensor 1 If you remove both of these there would now be a hole on each side for the exhaust to escape easier, it will be loud, but its just a test to see if engine has more power If so then Cats or muffler is clogged, usually Cats |
Just asking, as I am learning.Why aren't we thinking this isn't tranny related?

Failing torque converter would, for sure, cause OD OFF light to flash and no mention of that
You could test it Google: testing torque converter stall speed Simple test |

Then its a custom setup or its NOT a 1998 Ranger
1994 was the last year with P R N OD D 2 1 1995 and up had P R N D 2 1 1994 and earlier, seen here: https://i.ebayimg.com/images/g/wXsAA...HRI/s-l640.jpg 1995 and up, seen here: https://cimg2.ibsrv.net/gimg/www.ran...0e3a49225.jpeg They used different valve body but same transmission, 1986 to 1994 A4LD, 1995 and up 4R or 5R series In either case you can do the stall speed test |

I apologize your exactly right it’s a 1994 not a 98. I don’t know what the hell I was thinking but the title says 94 sorry bout that

1994 adds alot more things to look at
You have an A4LD automatic transmission, last year for it 3.0l has a distributor in 1994, last year for it, and a TFI spark system It needs to be timed with a timing light, SPOUT connector removed, base timing is 10 or 12deg BTDC, most prefer 12deg 1994 also runs 30-40psi fuel pressure with a fuel pressure regulator(FPR) on the engine You need to check the FPR's vacuum line, see if it has gasoline in it FPR looks like a small can, has the Return Fuel line and a vacuum hose connected, replace FPR if gasoline is found in vacuum hose It won't spin the tires, especially if its having engine power issues, but engine WILL stop REVing up when torque converter starts to lock So did it do that? |

In a 1994 there should be no O2 sensors after the Cats so they can be removed without any issue, as far as vehicle/computer is concerned
However its a Federal Law that requires Cat converter to be replaced if a vehicle came with them when new There are no Cat converter police, lol, so unlikely it would be an issue, but Exhaust Shops may not want to work on it after Cats are removed, its a $25,000 fine for them to remove cats and not replace them or to work on a vehicle that has no Cats and should have Many people remove the Cats then hollow them out and put them back in so it "looks like" Cats are there so no issues, unless you have to pass emissions testing This can also be cheaper than buying new exhaust pipes and fittings |

No, upstream O2s are all that a 1994 has and they won't care about Cats, or mufflers for that matter, lol

MPG should be 18 or so, so something is wrong, a clogged Cat would do that
3.0l Vulcan is a high RPM engine BY DESIGN Makes best torque/power at 3,700rpms Most engines do that at 2,700rpm So you really need to REV these engines, doesn't hurt them, in fact they always get carbon build up because people are always lugging them at 2,500 to 3,000rpm "Drive it like a rented Mule", lol Hard to do with an automatic but you can leave it in 2nd to get the RPMs up before shifting to drive 3.0l was much better in a manual |
