Celica Fuel Injection Problem

Hey, I'm having some trouble with my 2004 Toyota Celica (gasoline engine). It's got about 108k km on it. Recently, I've noticed a few things: my fuel consumption is way up, the engine feels like it's lost some power, and sometimes it even stalls when idling. Plus, I'm seeing some smoke when I accelerate, which is definitely not normal. I've checked the spark plugs and air filter, but they seem fine. I'm suspecting it might be something with the fuel injection system. Could be a faulty cable or plug connection? Anyone experienced anything similar with their Celica? Any thoughts on what I should check next?

Sounds like a potential injection system problem, alright. Increased fuel consumption and stalling are classic symptoms. You mentioned cables and plugs – that's a good starting point. Have you checked the fuel injectors themselves for any visible damage or leaks? Could also be a sensor issue feeding bad data to the ECU. Have you tried reading any error codes? That could point you in the right direction.

Thanks for the quick reply! I haven't actually checked the fuel injectors directly for damage or leaks yet, mainly because I wasn't sure how to get to them without potentially messing something up. As for the error codes, I haven't gotten around to reading them yet, to be honest. I don't have an OBD2 scanner myself. Is it worth buying one, or would I be better off just taking it to a mechanic to get the codes read? Also, where exactly are the fuel injectors located on this engine? Any tips on how to visually inspect them without causing more problems?

Okay, without an OBD2 scanner, you're a bit limited. Buying one is a good investment if you plan on doing more work on your car yourself in the future. As for the injectors, they're usually under the intake manifold. Visually inspecting them without proper tools can be tricky and you risk damaging something. Given your symptoms, and without being able to pull codes, I'd lean toward suggesting a workshop visit. Could be something simple, but fuel injection issues can be tricky to diagnose without the right equipment.

Alright, I think you're right. Probably best to take it to a workshop before I make things worse. Thanks a lot for your help! I took it to the workshop today and the mechanic found a defective cable connection on one of the injectors. After the replacement, which cost 95€, the car runs great again!
