How hard is it to replace the injectors i think the dealer might be right just asking if any one has done this o and is the cold start injector the same as the rest or not. It's a 91 runner with a 22re
Thanks

 

The cold start injector is up on the top and is a piece of cake.

The four main injectors (much different than the cold start injector) are not hard to replace, you just have to take the upper intake plenum off.

I did it a few weeks ago, it's not bad.

DON'T buy new injectors though, you will pay ALOT of money. Injectors are year-specific as well, so either get your own injectors cleaned or buy injectors from an engine of your same year, get those cleaned and balances, and do a swap - that's what I did.

www.witchhunter.com is a good company for that.

 

91 should use the later stye "high ohm" injectors...

I replaced mine with "lucas" disk stype injectors... more effort tho
-- solder in a new harness an clips
-- tweak AFM to LEAN it out more
-- add "Vf" guage to make sure the AFM is adjusted right...

Its not really that bad...

IMHO do a new fuel filter since its now alot easier to get to

 

i replaced the fuel filter two week's ago
does anybody know of a place near chicago that cleans injectors
this truck is my DD i can't have it down for the better part of a week

 

PM me...

I might have a spare set of injectors.

You'll need to read the PART NUMBER off the injector to make sure they are compatible...

If the numbers match... Send in the "spare" set to be cleaned and swap in the cleaned ones .... down time - labor time...

 

change them your self and if you go the route of pulling the thrott;e body off label the vaccume hoses
