conserved: Good mornin peeps, Just to be clear here...what exactly did you do to the fuel system? What did you change it to, and what was it to start with? What was wrong with the original fuel system? What engine size is it? |

He couldn't have done a good job...A good tech would solve the initial problem, not create more. I don't know how much your "mechanic" charged you, but all he's done is pretty much bent you over, and given you the rough end of a pineapple up your rectum. A transmission issue lead to an engine being down graded from EFI to carburettor! Jesus Christ. That's a 2,5 5 cylinder engine, it will be well under fuelled if running a carb. That carb will not supply enough fuel to keep that engine happy. Just because it's using less fuel, doesn't mean all is well. Your pistons will be cooked, due to running too lean. the 2,5 I5 is very different to the old 1,9 that was fitted to the early Volkswagen Santana / Passat. It was NOT designed to run with a carb. It was smoking initially, because it had a fuelling issue, not because it needed to be running on a carburettor. Now you're having starting issues, and not surprising. The 2,461cc I5 needs cold start enrichment, you've lost that with your "conversion" to carb. Unfortunately, I can't help you here. The best solution all round, would be to restore the original fuel injection and its ECU. It's automatic, and the tranny has its own control unit (TCU). The TCU computes gear changes by receiving signals from the engine ECU, so it knows what the revs and load are. It will not shift properly with the ECU missing. Your transmission TCU will be in limp mode right now, and it's only a matter of time before it stops altogether. Good luck. |
