Throttle Body COVERED in Oil. HELP!

I just recently bought a 97 toyota Tacoma 2WD Regular Cab pickup truck. The truck starts right up and runs nicely but was like a thousand fingers massage when idling (IE rough) so I dug around on the internet and found an article about cleaning the Throttle Body right here on Tacoma World. 2 bleeding knuckles and 30 minutes later I'm holding the throttle body in my hands and what a mess! The inside of the throttle was covered in oil. This oil was not dried gook but wet. I'm sitting down so give it to me. Thanks in advance for any help offered.

Not intimately familiar with the first generation tacomas, but if it was that bad, you should really consider removing your intake manifold to give it a good cleaning too, just make sure you have an extra gasket to re close everything back up. and your MAF (Mass Air Flow) sensor could probably use a good cleaning too since its in that area.

 

Never seen oil on a throttle body but def clean it. It could be just an accumulation of gunk that built up. Mine was black too

 

^ x2 on the intake manifold

 

no worries, One of the first gen guys should chime in here shortly

 

Alott of things could be done.... If your intake filter is stock I would recomend getting a drop in or CAI with a new filter. Like said clean the intake. Check or any leaks or broken seals.

 

^This, and you'd be amazed the difference a new fuel filter & air filter can make in preventing fouling of the rest of the engine components. Well worth the 15$ for the filters. Since you bought old, do you know the maintenance records at all?? or have a slight idea??

 

im pretty shur thats not oil but just years or dirt and grime built up. hit that bad boy with some deep creep and you will be good to go

 

Check PCV valve (might as well just replace it) and EGR system.

 

Clean the S H I T out of everything intake, whats your plugs look like ? I'd do a comp. test also

 

I bought it from a guy who used it as a second vehicle for moving audio equipment and yard care taking. One owner and he did most of the maintenance. Nothing big on the records. I put in a new air filter and replaced the plugs. I need to hunt down a fuel filter and I'm considering replacing the plug wires and cap. Thanks for everyones help, this place rules!

 

Welcome to TW

 

Looks like carbon buildup that never got cleaned off. Clean it off and it will be good to go. Don't waste your money on a CAI, there are little to no gains from CAIs on the first gens. Look up the deck plate mod instead.

 

Actually OP, since your here, do a lil reasearch on that, one of the best & cheapest upgrades available for the first gens

 

BrokenTusk, are you referring to the deck plate mod? I found a step by step and it looks fairly easy. Good huh?

So I cleaned the crap/S H I T outta that thing, tossed it back on and the hibby hibby shake is gone. It idles a little high but from what I've found online, that'll correct itself. Thanks again everyone! I thought I was hosed!

 

My TB looked the same. 200,200 miles and doesn't burn a drop of oil. I don't think either of our TB's were ever cleaned. Just sprayed with the engine running. I took mine off and cleaned it like you are, idles much better.

 

seafoam the crap outta that truck...I'll bet you would be smoking for about 30 mins and the entire neighborhood.

Just purchased a 4 banger with 90K - idle ran rough in the beginning and gas mpg was horrible - changed sparkies (they were in need of new plugs), seafoamed - mpg about 400 miles to a tank of gas, idle is a lot smoother. Oh yeah, did the deck plate mod over the weekend....could hear the drone, not sure what it did to hp or mpg, but nevertheless, pretty simple to do and did everything including the cleaning, cutting the box, installing, etc. in about 40 mins.

 

^^^yep......seafoam the shit outta the motor. replace the pcv valve too.......and your idle will improve.
