I have a '97 1.8 with new: fuel pump, fuel filter, injectors, CPS, plugs and wires. It had a terrible problem running last year and took it off the road. I've slowly fixed/replaced things (injectors were FULL of mud so I redid most of the fuel system!)

Now it starts up and idles nice and I can rev it up nice but the first moment I rev it, it stumbles and clears itself up. I can rev it up after it stubles, let it settle down and rev it up with another stumble.

If I let it idle a minute, it'll stumble again just off-idle. If I was in gear and tried to drive off, it'd almost stall unless I reved it up and rode the clutch a bit.

BTW, No CELs even with the fuel injectors clogged with crap and it running terribly.

 

i got the same problem right now. i bought a new tps and once it gets here ill see if that fixes it.

 

Cool. I'm gonna check my plug gap as well.

I'm going to pick up a can of Seafoam tonight and get some good, new gas in the tank.

 

Are you sure that your MAF is oriented in the right direction?

 

It's never been off since I owned it. How can I know for sure?

 

There's an arrow on the MAF indicating proper direction.

I'd definatly check your plug gap. I'd also check for vacuum leaks. Do you have a CEL?

 

no CELS

 

wut if my maf sensor is not in the housnig anymore. I have it bolted in my charge pipe for my IC piping. how will ik if its backwards or not without the housing for it?

 

Sounds like the usual culprit, the TPS. Test it.

 

how do u test the TPS?
