I have a 1990 Laser 1.8L. just picked it up for 350$ (So Cheap because It wont pass emissions at the moment, and doesn't run right, and its not the pretties to look at because paint is peeling, hood is black Which i dont mind, and the fake front lights are missing..). Owner put a lot of work into it, he rebuilt the motor a few months ago, along with aftermarket Hi-Comp Pistons (or so he says), and it has just sat most the time since, due to other problems he'd thought would be fixed after rebuild...

I drove the car home which was a 45 Min drive, it handled it with out a problem, never puffed out smoke or anything, never over heated either.

The Problem I'm having is it has a bad miss. Cyl 1 comes and goes, but stays out most of the time. dead cyl would kick in and stay for about 5 mins then go out again during cruising.

The Symptoms I have are just strong smell of gas, loss of power and efficiency, and it sounds like a Boxer Engine.

The Plugs + Wires are brand new, the Distributor is clean, w\ new rotor and Cap, I have thick blue spark across all 4 cylinders.

No signs of a Blown Head Gasket, no smoke, no coolant in my oil, and I did a Compression Test and it came out

1: 190 Psi
2: 192 Psi
3: 192 Psi
4: 191 Psi

I have Injector Pulse across all 4 cylinders, Cyl 1 injector seems little iffy as far as the pulse goes, idk how to explain it though just sounds weird through the stethoscope compared to the other 3. The previous owner said the whole fuel system could probably use a change so I'm going to the local pull yard this weekend and pulling Injectors, Fuel Rail, FPR, Fuel Pump, and Fuel Wiring Harness. Hopefully that solves the problem but I was hoping for some Ideas.

The Previous owner also said that the car use to have a EGR Valve but he removed it, Could this have anything to do with it? I'm still learning certain things about cars so bare with me please.

Thanks.

Question: Would Turbo Injectors + Fuel Pump be Bad for my engine? From what I understand it would be fine because they will both only put out as much as the Computer Allows\Tells them too. I would like a 2nd opinion though.

Oh, Also told that the Engine hasn't been fully broken in yet... Dunno if that helps you guys out or not.

Please help me tho.
 
My 1.8 has a dead cylinder once in a while also and I have yet to figure it out. I have replaced the plugs, wires, cap, and rotor just like you and it still does it just vary rarely. I would try a different injector if the one sounds funny. It will need to be replaced with another stock 1.8 fuel injector because the ecu is not programmed to compensate for a larger one.
 
If your fuel pump is working I wouldn't even mess with it honestly.

It was just a thought cause, who know's how long the stock one last's, and I'm going to need a better fuel Pump soon because I plan on doing a 4g64 swap into my laser this spring.

Thanks for the help.

If anyone else has something they wanna say please feel free to do so.
 
Good luck with the swap...tonnage of work there, including ECU and harness.. - DSM

Thanks for the Input.

Not too worried about that. I can order a 4g64 w\ Tranny + ECU + Mounts + Wiring Harness for less then a 4g63T alone excluding shipping

no worse then a average Honda swap, and I'd have to do the same work to do a 4g63T or N\T swap according to the threads on here.

I don't really think of swaps as work, they are challenging fun in my mind LOL.
 
...and that is what counts. Good luck and have some fun then .. - DSM

I actually might be getting rid of the car already LOL.

Friend of mine is selling his Turbo Laser, 6 bolt 4g63T FWD, BTU's, 5 Speed, motor runs iffy as well but we're both sure its the MAF

500$ + Trade for my Laser
