22re timing help

[tdr racing]

My timing for my 94 toyota truck is off. I've heard I need to adjust my distributor. I've also heard I need to jump some coil wires or something like that. Anyone have an idea on what it's about?

EFI or carbed?

You need to disable the electronic advance. You do this by putting a jumper wire between two terminals in the check connector. Doing this disables the electronic advance. Then you put the timing light on and check the timing, adjusting is by rotating the loosened distributor. When the timing is to specs (w/ advance disabled), tighten your distributor and remove the jumper wire.

Check your manual also....

Hope this helps

I posted this a while back as I had the same thing happening. The problem lies in the tps! The throttle has to be closed at idle when the connectors are jumped in the data link to get the timing right. Mine was not closed and my timing was way off, adjusted it and now good. Bear in mind that the timing guides may be broken and the timing will be erratic. If you address a plastic guide problem, buddy do yourself a big favor,you deserve it, close you eyes and throw whats left of the plastic guides as far as you can and don't go look for them. Replace the with steel based guides from your local speed shop at about 60.00 for the pair. Some other tips if you do the job, ask! Tim

First clean throttle body if problem persists re-adjust TPS if problem still there then replace TPS but pull the ECU codes first to verify that code 11 is present telling you the TPS is bad and once you replace it recheck your engine timing.

To clean the throttle body remove the air intake hose and examine the intake and throttle body for excessive carbon build if found then buy a can of throttle body cleaner labeled "safe on oxygen sensors,TPS's and catalytic converters" and make sure your engine is fully warmed up prior to using as when the throttle body is hot it dissolves the carbon easily and quickly.The labels usually specify to park the vehicle at groung level (0 degrees,no inclination) and have the engine running but I disagree I instead park the vehicle on a hill facing down and shut the engine off and hold a rag below the lip of the throttle body and poor the stuff and use a tooth brush.

Normally you can re-adjust the TPS:

and not replace it but re-check you timing after you change it as it can retard your engine timing my as much as 10 degrees and cause your engine to overheat.At least one day before re-adjusting or replacing TPS spray both Philips screws with a deep penetrating lube several times:

1)PB Blaster
2)Liquid Wrench
3)Kroil Oil
4)Aero Kroil & Sili Kroil
5)Toyota Rust Penetrant or High Performance Penetrating lube
6)Rust Check

About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes and auto tranny computer codes to see if a fault is registered.
To pull the ECU codes:

All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.

Any Public Library in your area would have the Factory service manual,Haynes,Chiltons,Mitchells,Clymers,Bentley and Toyota repair books.

There is also free AutoZone service manuals at:

FSM (factory service manual)can be acquired in several ways:

Toyota Material Distribution Center

1)buy a used one off e-bay
2)some Toyota dealerships may give you one or sell it for $10-20 (used) as most Toyota dealerships don't repair many old Toyotas and no longer need the service manual
3)some public libraries sell their old books as they are not in demand any longer
4)some free buy & sell classified papers,websites and bulletin boards may have some used ones for sale
5)some junk yards may have one laying around
6)some Toyota specialty garages may have one laying around and no longer use it as the vehicle may be too old and those mechanics probably have so much experience that they could publish their own factory service manual with corrections and "real world repair tips"
7)if someone has the FSM maybe they could scan all of the pages and post it on a site for all of us to download or view.
