When I rebuild an engine I use the opportunity to send the fuel injectors to a professional testing and cleaning company. Last I used was Witch Hunter. Maybe one or two injectors are not giving good spray pattern. If one cylinder misses try switching injectors to see if that cyl. improves.

 

I am going to run a check on the IAC valve next.

 

IAC checks out good. I talked to the cousin and I have done everything he could think of except checking the MAP sensor pins. Tomorrow.

 

I took the car to a local mechanic and he fixed it, he said the exhaust cam was 40 degrees out. I swear I double checked it but those little marks are hard to see. I would suggest to anyone mark the alignment dots with something bright before disassembly. The mech says it purrs like a kitten.

Hey im new to this forum.I have a 1994 camry its a 4 cylender and 1 and 2 cylender are not firing they are getting spark i cleaned out the distributor cap and all four are sparking good it does run but only on 3 and 4 cylender. I was wondering if anyone new what the problem could be the problem its just running rough when i have it running i can pull out the 1 and 2 spark leads and nothing at all changes in the motor if i take out 3 or 4 it stalls.

 

Use a section of rubber hose as a stethoscope and listen for No 1 and 2 cylinder injector noise. Make sure they are making a clicking noise when the engine is running.

Crank the engine over with the plugs out then check for signs of fuel in the No 1 and 2 cylinder.

Have you checked for compression in these 2 cylinders.

Are the plugs wires connected at the distributor cap in the correct order?

 

Yes i have checked to male sure all plug wires in order what happened was my father was driving it and he stopped at lights then the motor just died he thought he was out of fuel then he finnaly got it to start and it was running on 2 cylenders from then on ill do that thing with the house and a compression check on then to thanks mate.

 

This helped me to no extent. I was working on a coustomers car and was about to bomb the damn thing then i popped open the valve cover and i was one tooth off on the camshaft. very very good info. Thank you
